PROPOSED CHANGES TO ONTARIO REGULATION 213/91, CONSTRUCTION PROJECTS, UNDER THE OCCUPATIONAL HEALTH AND SAFETY ACT
FOR IMPROVING TOWER CRANE SAFETY
AS RECOMMENDED BY THE TOWER CRANE REGULATION REVIEW WORKING GROUP
CURRENT REQUIREMENT IN O. REG. 213/91
NO definition of “climbing”
PROPOSED CHANGES RELATED TO TOWER CRANES
NEW DEFINITION
“climbing” means the process in which a tower crane working on or
within a structure that is under construction, as the height of that
structure increases, the tower crane is raised to a new working
height by changing the elevation of the crane superstructure and
includes top-climbing, bottom-climbing, internal climbing and
telescoping.
NO definition of “mobile crane”
NEW DEFINITION
“mobile crane” means a mechanical device or structure that
incorporates a boom that,
(a) Is capable of moving in the vertical and horizontal plane,
(b) Is capable of raising, lowering or moving a load suspended from
the boom by a hook or rope, and
(c) Is mounted on a mobile base or chassis,
RATIONALE/COMMENT RE: PROPOSED CHANGES

A proposed definition of “climbing” is being added and is a
combination of the definitions from the CSA standard Z248-04,
Code for Tower Cranes, and the United States Occupational
Safety and Health Administration (OSHA) Regulations.

The term “extending” a tower crane (terminology currently
used in section 154 of the Construction Regulation) which has
traditionally meant external “top-climbing” of a tower crane, is
being replaced with “climbing” (as defined) to avoid confusion
over the different types of “climbing”.
A proposed definition of “mobile crane” is being added,

consistent with the one in O. Reg. 275/11, Scope of Practice –
Trades in the Construction Sector, under the Ontario College of
Trades and Apprenticeship Act, 2009,
 to clarify when particular requirements apply specifically to
mobile cranes and not to other types of cranes e.g. operator
qualifications specified under the OCTAA.
and includes a telescoping or articulated boom but does not include
equipment that is used exclusively for fire-fighting or by automotive
wreckers and tow trucks to clear wrecks and haul vehicles.
NO definition of “self-erecting tower crane”

NEW DEFINITION
“self-erecting tower crane” means a tower crane that is capable of
being erected without the use of ancillary equipment.

RATIONALE/COMMENT RE: PROPOSED CHANGES
NEW Item 12 – A new incident is added for which a constructor
would have to provide a written report to the Ministry and to a Joint
Health and Safety Committee, health and safety representative or
trade union, if any, within 2 days of the incident, setting out the
circumstances of the occurrence and the steps taken to prevent a
recurrence. There appears to be a recent increased incidence of
suspended loads being dropped by cranes. Such incidents can
have catastrophic results on workers and property. This addition
would provide the Ministry an opportunity to follow up on particular
incidents to determine whether they involved any violations of the
Construction Regulation.
New ss.(1.1) – If a decision is made by the constructor and tower
crane employer that the tower crane on a project could be used if
necessary in the event of an emergency situation to rescue a
worker from an elevated position on the building or structure under
construction, then that must be clearly indicated in the emergency
procedures and appropriate details provided. The constructor and
employer would have to ensure that the tower crane and platform,
basket, stretcher or other rescue device used to rescue a worker
meet the requirements in NEW subsection 153.1.
102. No operator shall leave unattended the controls of,
(a) a front-end loader, backhoe or other excavating machine with
its bucket raised;
(a) a front-end loader, backhoe or other excavating machine
with its bucket raised;
(b) a bulldozer with its blade raised;
(b) a bulldozer with its blade raised;
(c) a fork-lift truck with its forks raised; or
(c) a fork-lift truck with its forks raised; or
(d) a crane or other similar hoisting device with its load raised.
(d) subject to s.164, a crane or other similar hoisting device with
its load raised.

A cross reference to section 164 is added. S.64 is being changed
to allow a load to be suspended from an unattended tower crane
only if specified by the crane manufacturer.

CURRENT REQUIREMENT IN O. REG. 213/91
Amended March 2013, came into effect April 8, 2013 to align
with the Ontario College of Trades and Apprenticeship Act,
2009 coming into effect on the same date.
150. (1) Subject to subsection (2), no worker shall operate
a crane or similar hoisting device unless the worker holds a
certificate of qualification issued under the Ontario College of
Trades and Apprenticeship Act, 2009, that is not suspended, or
the worker is an apprentice and is working pursuant to a training
agreement registered under that Act, that is not suspended, in
the trade of,
(a) hoisting engineer — mobile crane operator 1, if the worker is
operating a crane or similar hoisting device capable of
raising, lowering or moving any material that weighs more
than 30,000 pounds;
(b) hoisting engineer — mobile crane operator 1 or hoisting

PROPOSED CHANGES RELATED TO TOWER CRANES
150. (1) Subject to subsections (1.2) and (2), no worker shall
operate a mobile crane or tower crane or similar hoisting device
unless the worker holds a certificate of qualification issued under the
Ontario College of Trades and Apprenticeship Act, 2009, that is not
suspended, or the worker is an apprentice and is working pursuant
to a training agreement registered under that Act, that is not
suspended, in the trade of,
(a) hoisting engineer — mobile crane operator 1, if the worker is
operating a crane or similar hoisting device capable of raising,
lowering or moving any material that weighs more than 30,000
pounds;
RATIONALE/COMMENT RE: PROPOSED CHANGES
Section 150 is revised to clarify that the operator qualifications
specified under the Ontario College of Trades and Apprenticeship
Act, 2009 apply only to operators of mobile cranes and tower
cranes and not to any other types of cranes or hoisting devices.
(b) hoisting engineer — mobile crane operator 1 or hoisting engineer
— mobile crane operator 2, if the worker is operating a crane or
similar hoisting device capable of raising, lowering or moving
only material that weighs more than 16,000 pounds but no more
than 30,000 pounds; or
(c) hoisting engineer — tower crane operator, if the worker is
operating a tower crane.
(c) hoisting engineer — tower crane operator, if the worker is
operating a tower crane.

NEW (1.1) Subject to subsection (1.2), an apprentice operating a
tower crane shall be constantly monitored during the operation
of the crane by a person who:
(i)
meets the requirements of ss.(1)(c),
(ii)
is in direct audio communication with the apprentice,
(iii)
is not engaged in performing other work while
monitoring the apprentice who is operating the crane, and
(iv)
is able to direct the apprentice during the operation
of the crane.
1.1) Subsection (1) does not apply when a worker is using
excavation equipment to place pipes into a trench.
4
In NEW subsection 150(1.1),
o
The monitor would not have to be in constant
visual contact of the apprentice operator since there may
be situations when their views of each other are blocked
by objects/structures on the construction site during the
movement of a load by the crane.
o The term “during the operation of the crane” means while
the apprentice is manipulating the controls of the crane
and the controls are “ON”. The intent is for the monitor to
be able to tell the apprentice to immediately stop the
operation at any point should an unsafe situation develop.
o The reference to “not engaged in performing other work” in
paragraph (iii) would allow the monitor to do work related
to the hoisting operation e.g. guiding a load being moved
or unhooking a load placed by the apprentice.
May 15, 2013
CURRENT REQUIREMENT IN O. REG. 213/91
(1.1) Subsection (1) does not apply when a worker is
using excavation equipment to place pipes into a trench.
PROPOSED CHANGES RELATED TO TOWER CRANES
RATIONALE/COMMENT RE: PROPOSED CHANGES

Deleting existing subsection (1.1) does not change the current
intent or implementation of the requirement. Subsection (1.1) is
deleted because the Ministry has determined that excavation
equipment used to place pipes into a trench is not a crane or a
hoisting device similar to a crane, and section 150 is being
changed so it would no longer apply to “similar hoisting device”
i.e. it would only apply to mobile and tower cranes.

The NEW subsection (1.2) would make it mandatory for
operators of self-erecting tower cranes to have completed the
MTCU training programs for self-erecting tower cranes
released in 2009. The specific titles and identifying numbers of
the training programs are not included in the Regulation as they
may be updated/changed at any time by MTCU.
New (1.2) An operator of a self-erecting tower crane,
(a) rated more than 40 metre tonnes, shall hold a certificate of
qualification issued under the Ontario College of Trades and
Apprenticeship Act, 2009, that is not suspended in the trade of:
(i)
hoisting engineer — mobile crane operator 1, or
(ii)
hoisting engineer — tower crane operator, and
(b) rated up to and including 40 metre tonnes, shall hold a
certificate of qualification issued under the Ontario College of
Trades and Apprenticeship Act, 2009, that is not suspended in
the trade of:
(i)
hoisting engineer — mobile crane operator 1, or
(ii)
hoisting engineer — mobile crane operator 2, or
(iii)
hoisting engineer — tower crane operator, and
(c) shall have successfully completed the relevant modular training
standard developed and administered by the Ministry of
Training, Colleges and Universities for self-erecting tower crane
operator.
(2) No worker shall operate a crane or similar hoisting device,
other than one described in subsection (1), unless,
(a) the worker has written proof of training indicating that
he or she is trained in the safe operation of the crane
or similar hoisting device; or
(b) the worker is being instructed in the operation of the
crane or similar hoisting device and is accompanied by
a person who meets the requirements of clause (a).
(3) A worker shall carry his or her proof of training while
operating a crane or similar hoisting device.
(2) No worker shall operate a crane, other than one described in
subsection (1), or similar hoisting device unless,
(a) the worker has written proof of training indicating that he or she
is trained in the safe operation of the crane; or
(b) the worker is being instructed in the operation of the crane or
similar hoisting device and is accompanied by a person who
meets the requirements of clause (a).
(3) A worker shall carry his or her proof of training, or qualification
issued under the Ontario College of Trades and Apprenticeship Act,
2009, while operating a crane or similar hoisting device.

CURRENT REQUIREMENT IN O. REG. 213/91
151. (1) No crane or similar hoisting device shall be
subjected to a load greater than its rated load-carrying capacity.
(2) The manufacturer of a crane or similar hoisting device
or a professional engineer shall determine its rated load-carrying
capacity in accordance with,
(a) for a mobile crane, Canadian Standards Association
Standard Z150-1974 Safety Code for Mobile Cranes;
and
(b) for a tower crane, Canadian Standards Association
Standard Z248-1976 Code for Tower Cranes.
(3) Every crane or similar hoisting device shall have
affixed to it a load rating plate,
(a) that the operator can read while at the controls; and
(b) that contains enough information for the operator to
determine the load that can be lifted for each
configuration of the crane.
(4) A luffing boom crane, other than a tower crane, shall
have affixed to it a boom angle indicator that the operator can
read while at the controls.
152. (1) The owner of a crane or similar hoisting device
shall keep a permanent record of all inspections of, tests of,
repairs to, modifications to and maintenance of the crane or
similar hoisting device.
PROPOSED CHANGES RELATED TO TOWER CRANES
RATIONALE/COMMENT RE: PROPOSED CHANGES
151. (1) No crane or similar hoisting device shall be subjected to a
load greater than its rated load-carrying capacity.
(2) The manufacturer of a mobile crane or tower crane or similar
hoisting device or a professional engineer shall determine its rated
load-carrying capacity in accordance with, as appropriate,
a) for a mobile crane, Canadian Standards Association Standard
Z150-1974 Safety Code for Mobile Cranes; and

ss.(151(2) – The revision is necessary since the referenced
CSA standards apply only to mobile cranes and tower cranes
and not to “similar hoisting devices”.
(b) for a tower crane, Canadian Standards Association Standard
Z248-1976 Z248–04, Code for Tower Cranes.
(3) Every crane or similar hoisting device shall have affixed to it a
load rating plate chart,

ss.(3) – The existing term, “load rating plate” is replaced with
the term, “load rating chart” for consistency with the CSA
standard Z248-04, Code for Tower Cranes. This same
editorial change is made throughout the regulation to ensure
consistency and would apply to all cranes. This revision would
not change the existing intent or interpretation of the
requirements.

ss.(4) - Deleting “other than a tower crane” means all luffing
boom cranes, including luffing tower cranes, would need to
have a boom angle indicator. This change reflects the
changing technology of tower cranes since the initial
introduction of this requirement in the Regulation. Industry
experience indicates most new luffing tower cranes have
digital boom angle indicators at the operator’s controls. Older
cranes that do not have boom angle indicators may need to
have them retrofitted in order to comply with this requirement.

Section 152 is revised based on CSA standard Z248-04, Code
for Tower Cranes, Clause 6.2, to provide clarity regarding the
creation and maintenance of the machine history of a crane
and the crane’s log book. Although section 152 applies
generally to any crane and not just to tower cranes, the Tower

performed; and
(b) be considered a permanent part of a crane that is to be
transferred to each subsequent new owner of the crane.
(2) The owner of a crane or similar hoisting device shall
prepare a log book for it for use at a project that shall include the
record referred to in subsection (1) covering the period that is the
greater of,
(a) the immediately preceding twelve months; and
(b) the period the crane or similar hoisting device is on

RATIONALE/COMMENT RE: PROPOSED CHANGES
Crane Regulation Review Working Group would like to
recommend that industry consider these proposed
requirements for all cranes and not just tower cranes. The
revisions would not impose new obligations but would simply
clarify in regulation what is routinely currently done in practice
with respect to crane inspection/maintenance records by crane
owners and crane users/operators while a crane is on a
project.

the above listed activities e.g. professional engineer inspecting the
crane, mechanic/technician servicing the crane. Currently, the
crane owner only has to provide the information to the constructor
on a project. Professional engineers would need to refer to these
records in order to comply with engineers’ expanded inspection
requirements for tower cranes proposed in sections 158, 159, and

NEW Ss.153(8.1) – If a tower crane is to be used to hoist a worker
on a man basket or platform, an engineer must inspect more than
just the structural components of the crane prior to the crane
hoisting a worker i.e. the engineer must inspect the same items as
noted in revised s.159 in accordance with the Practice Standard for
Tower Crane Review developed by the Professional Engineers of
Ontario (PEO) in consultation with the Tower Crane Regulation
Review Working Group rather than “good engineering practice”.
The Practice Standard is meant to guide professional engineers in
their inspections of tower cranes (see sections 158 and 159 for fully
explanation). A tower crane that complies with the proposed s.158
and s.159 (inspected by an engineer before and after its erection
and at least every 12 months after that) would be considered in
compliance with the inspection requirement in ss.153(8.1).

any self-erecting tower crane, being placed into service on
the project; and
(b) At least seven (7) days prior to the tower crane, excluding
any self-erecting tower crane, being dismantled.
This new requirement is being added at the Ministry of Labour’s
direction. To facilitate compliance, the Ministry would develop a
notification form (paper and electronic) that a constructor would be
able to mail (by conventional or electronic means), fax or deliver in
person to the ministry office located nearest to the project.
(2) The notification shall specify the:
(a) the address of the project at which the tower crane is to be
operated/used;

New design specifications for tower cranes are being added,
supported by a revised and more rigorous inspection regime and
new verification process by engineers, to ensure tower cranes will

the ESA’s Electrical Specification for Tower Cranes and the control
equipment requirements in ss.156.(1)(b) and (c).
(b) shall comply with the requirements in ss.(1)(b) and (c).

implementation period be e.g. 2 years? Industry is being
asked to provide feedback to the Provincial LabourManagement Health and Safety Committee on how much time
would be reasonable to give to crane owners to enable them to
bring their existing cranes into compliance with the new
design requirements.
Tower cranes in service on a project when the new proposed
requirements come into effect, would be allowed to continue to
operate. However, once their work is completed and they are
dismantled and removed from a project, they would also have to be
reviewed and brought into compliance with the new design

CURRENT REQUIREMENT IN O. REG. 213/91
PROPOSED CHANGES RELATED TO TOWER CRANES
RATIONALE/COMMENT RE: PROPOSED CHANGES
QUESTION TO INDUSTRY: The regulation of tower cranes in
Europe has historically required more rigorous inspections of
older cranes. Anecdotal evidence indicates that crane owners,
rather than undergoing the expense of these rigorous
inspections, often sell their cranes instead which are
subsequently sometimes brought to Ontario. The Ministry’s
past tower crane blitzes indicated that many older cranes were
not being properly maintained and as a result, exhibited
defects. Industry is being canvassed for feedback whether
there is a need for more thorough inspections for older tower
cranes as well as after a tower crane undergoes a major
alteration.
1. Should tower cranes be required to undergo a more
thorough inspection than the annual inspection regime
specified in the Practice Standard for Tower Crane Review
developed by the Professional Engineers of Ontario after
they reach a certain age and/or after a major alteration
and/or after a serious defect has been identified?
1. What should be included in this more thorough
inspection?
2. What should be the minimum age of a crane before it
would be required to undergo a more thorough inspection
e.g. 10 yrs? 15 yrs?
3. How often should an older crane be required to undergo a
more thorough inspection e.g. every 3 yrs? 5 yrs?
4. What is meant by “a major alteration” and “serious
defect”?

19
RATIONALE/COMMENT RE: PROPOSED CHANGES
A stronger inspection regime is being proposed for tower cranes.
Ministry of Labour’s past enforcement experience indicated defects
and unsafe conditions in not only structural elements of tower
cranes but also in their electrical, mechanical (e.g. hoists) and
hydraulic components and systems as well as control systems. For
this reason, the current inspection requirement is being expanded
beyond structural elements of tower cranes.
In addition, Ministry’s past tower crane enforcement campaigns
indicated tower cranes were being inspected by professional
engineers, as required by section 158, in an inconsistent manner
and that engineers’ inspection reports varied greatly. To address
this inconsistency, the Professional Engineers of Ontario (PEO)
developed a Practice Standard for Tower Crane Review, in
consultation with the Tower Crane Regulation Review Working
Group, to guide professional engineers in their inspections of tower
cranes (see attached document). The attached Practice Standard
is still a draft but very close to being completed. The finalized
Practice Standard is not expected to be much different from the
attached draft version. Once finalized by the PEO, the Practice
Standard is expected to be made into a regulation under the
Professional Engineers Act which would replace the current
reference to the Practice Standard in the final proposed
amendments to the Construction Regulation. Professional
engineers would then be required to follow the new regulation
under the Professional Engineers Act when inspecting tower cranes
in compliance with the Construction Regulation.
The phrase, “or a competent worker designated by a professional
engineer” is being removed at the request of the PEO as it is not
consistent with the Professional Engineers Act. The PEO is
expected to clarify shortly (and before the proposed amendments
are finalized by the Ministry) whether an additional phrase should
be added consistent with the Professional Engineers Act which
currently allows a professional engineer to delegate
duties/functions to a designated person who is under the engineer’s
direct supervision.

re: the use of rotation-resistant wire rope used on tower cranes,
consistent with CSA standard Z248-04, Code for Tower
Cranes, Section 4.11.

Subsection 168(5) is deleted since a damaged inner wire or
strand of a cable cannot be seen by a visual inspection.

The addition of a new requirement regarding swivels is based
on industry experience and the CSA standard Z248-04, Code
for Tower Cranes. However, unlike the CSA standard clause
4.11.2(h), the section requires that the use of swivels must be
allowed by both crane AND wire rope manufacturers. If either
the crane or wire rope manufacturer recommends that swivels
not be used with its respective product, then swivels must not
be used on boom hoist cable. The CSA standard allows the
use of swivels if either the crane OR rope manufacturer permits
swivels to be used.

170. (1) All cable used by a crane or similar hoisting
device shall be visually inspected by a competent worker at least
once a week when the crane or similar hoisting device is being
used.
(2) The worker performing an inspection shall record the
condition of the rope or cable inspected in the log book for the
crane or similar hoisting device.

used by a crane or similar hoisting device shall be visually inspected
by a competent worker as frequently as recommended by the cable
manufacturer and in any case, at least once a week when the crane
or similar hoisting device is in service.
The changes to ss.170(1) clarify that cable on tower cranes has
a more detailed inspection requirement in ss.161(8) and cable
on all other cranes must be visually inspected at a minimum of
once a week or more frequently than once a week if so
recommended by the cable manufacturer.

The addition of “epoxy resin” in ss. (1)(b) reflects current
technology in end terminations in the industry. The
amendment would not change the intent of the requirement
which applies to cable used by any type of crane, not just tower
cranes.
(2) The worker performing an inspection shall record the condition
of the rope or cable inspected in the log book for the crane or
similar hoisting device.
171. (1) A cable used by a crane or similar hoisting device
shall be securely attached,
(a) by binding and fastening the cable around an oval
thimble in a way that is strong enough to prevent the
cable thimble from separating; or

with a wire rope clip at the dead end to prevent the
accidental release or loosening of the wedge.
(b) by fastening the cable within either a tapered socket by means
of virgin zinc, epoxy resin or a wedge-type socket fitted with a
wire rope clip at the dead end to prevent the accidental release
or loosening of the wedge.
(2) The dead end cable of a wedge socket assembly on a
hoisting line shall extend between 100 millimetres and 300
millimetres out of the socket.

(2) UNCHANGED;
(3) (a) NEW A wire rope pendant cable on a tower crane shall have
all new wire rope terminations proof tested after installation onto
the wire rope in accordance with the recommendations of the
wire rope or termination manufacturer, but in no case to more
than 50% of the wire rope’s nominal or minimum rated breaking
strength; and,
(b) permanent records of the proof testing in clause (a) shall be kept
for the life of the terminations.

NEW ss.171(3) is consistent with CSA Z248-04, Code for Tower
Cranes, section 4.11.2 and reflects the critical nature of
terminations on pendant cables.
