Does the City of Toronto accept ISO 45001 on construction tenders?
Yes. From 31 March 2025 the City lists ISO 45001:2018 as one of three acceptable OHSMS certificates, alongside IHSA COR® 2020 and Ontario’s SOSE program. The ISO certificate must come from a body accredited by an IAF-recognized accreditation body. The City can still ask for the audit report.
