S
ome committees that work for 
health and safety improvements 
have a direct line to those who 
set the law.
Section 21 of Ontario’s Occupa-
tional Health and Safety Act (OHSA) 
gives the Minister of Labour, Im-
migration, Training and Skills De-
velopment (MLITSD) the ability to 
appoint committees to offer advice 
on anything that comes up under the 
Act or to look into anything else that 
they request.
There are two Section 21 commit-
tees in the industries that IHSA serves:
• The Provincial Labour-Manage-
ment Health and Safety Com-
mittee (PLMHSC); and
•  The 
Provincial 
Labour-
Management Safety Committee 
for Electrical and Utilities 
(PLMSC-EU). 
Their 
bipartite 
memberships 
– meaning equally made up of la-
bour and management representa-
tives – meet monthly to provide the 
MLITSD with input on industry-
wide safety priorities.  
Both committees set strategic direc-
tion for IHSA’s wider Labour-Man-
agement Network, while focusing 
their own efforts on high-impact ac-
tivities, such as advocating for revisions 
to training standards (e.g., working at 
heights, rigging, powerline work) and 
laying the groundwork for regulatory 
improvements. They engage directly 
with the MLITSD on technical re-
views and proposed amendments to 
the OHSA and the Regulation for 
Construction Projects (O. Reg. 213/91). 
The Construction Legislative 
Review Committee, a subcom-
mittee of the PLMHSC, often 
carries out the work related to 
the Regulation for Construc-
tion Projects by reviewing and 
refining submissions for regula-
tory change before they go to the 
MLITSD. This process makes 
sure that proposals are technical-
ly sound and based on real work-
place experience.
Importantly, the Section 21 
committees also serve as hubs 
for cooperation among industry, 
government and system partners. 
They maintain ongoing relation-
ships with the MLITSD, the 
Workplace Safety and Insurance 
Board (WSIB), colleges, unions 
and trades councils.
Because these committees are 
established and recognized by pro-
vincial legislation, their work and 
insights carry significant author-
ity – giving them unique powers to 
work for systemic health and safety 
improvements in the construction 
and electrical utilities sectors. 
Driving Legislative Change
The Labour-Management Net-
work has consulted on and pro-
moted awareness of many impor-
tant health and safety developments 
since 2024, including:
•  The first annual report of 
the Construction Death Re-
view Committee;
•  Regulation for Construction 
Projects (O. Reg. 213/91) 
amendments on crane safety 
and menstrual product avail-
ability on jobsites;
•  Proposed changes to the 
Coroners Act (R.S.O. 1990, c. 
C.37) and Ontario’s Build-
ing Code (O. Reg. 332/12);
•  Updates to the Electrical 
Utility Safety Rules and Util-
ity Work Protection Code;
•  Working for Workers Five 
Act and Working for Work-
ers Six Act; and
•  Transportation of Dangerous 
Goods Regulations.
