Ontario OHSA Compliance Checklist

• Public-sector buyers: aware that an inspector can impose a penalty without going to court for a breach of s.3 of O. Reg. 364/25 (the lesser of $100,000 and 10% of the contract value)
• Aware the Minister may publish the name of a person who receives an administrative penalty

This is the only penalty the regulation currently prescribes. It is not a general penalty regime for employers.

• Confirmed whether the rule applies to the work you bid on: it covers construction procurement only, by the Province and listed public bodies
• Your COR 2020 or ISO 45001 certification is current and audit-ready
• You know those buyers must treat all Chief Prevention Officer-accredited OHS systems as equivalent (as of October 2025: ISO 45001:2018, CSA Z45001-19, IHSA COR 2020, RC14001:2023 and RCMS:2023)
• You are not paying for duplicate certifications to satisfy a single construction tender
• Certificates and audit reports are ready to submit with bids

• Assessed whether the project runs 3+ months with 20+ workers regularly employed (AED required when both apply)
• AED plus the required accessories on site: 1 CPR mask, 1 pair of scissors, 2 pairs of disposable medical-grade gloves, 1 disposable razor, 1 garbage bag, 4 absorbent towels
• A CPR/AED-trained worker is present whenever work is in progress
• AED location is signed, and listed in the site emergency response plan (signage is required; the plan entry is good practice)

Quarterly inspection and record rules: see the Ontario AED construction checklist.

• AED was purchased between July 1, 2025 and June 30, 2027
• Proof of purchase and a copy of the project's approved notification form under O. Reg. 213/91 s.6(3) (or the ministry project number) are kept for the application
• Reimbursement claim (up to $2,500) submitted by July 31, 2027
• Aware reimbursement is limited to one defibrillator per project

• Assessed whether your own workers are at risk of an opioid overdose at work
• If at risk: at least one naloxone kit is provided on site
• Assigned worker(s) trained to recognize overdose and administer naloxone
• The risk assessment is documented even where a kit is not required

• Confirmed the requirement applies to you: constructors (s.23.1(2)) and all employers (s.25.3(3)), not construction only
• A cleaning record is maintained for each washroom facility
• The date and time of the two most recent cleanings are recorded
• The record is posted at or near the washroom, or posted electronically with directions to workers on how to find it
• Cleaning responsibility is assigned and understood

• CSA-approved respirators are accepted alongside NIOSH-approved ones (Reg. 833 s.10)
• Respirator fit-testing is current. Reg. 833 s.12 requires a fit test but sets no interval; the 2-year interval comes from CSA Z94.4, not Ontario law
• Construction head protection reviewed for O. Reg. 112/26 (from July 1, 2027: CSA Z94.1 or ANSI Z89.1 headwear, Type 2 where there are side-impact hazards)
• PPE purchasing specifications are reviewed as standards change

• OH&S policy is current, signed, and posted (6+ workers)
• Workplace harassment and violence programs are in place and reviewed
• A JHSC or health & safety representative is established and meeting
• Training records and incident / near-miss reporting are up to date

Applicable checks completed: / 32   Checks that do not apply:

Sections 1 to 4 apply to construction work or construction projects. Sections 5 to 8 can apply to any workplace; section 6 applies to all employers. Subtract items that do not apply and score the rest. Bands are proportional (about 87% and 63%).
