Approved Working at Heights Training Providers in Ontario

Before you book

Approval is not permanent and it is not retroactive. A provider on this list today may not have been approved when a worker trained two years ago, and a provider that has since been removed still delivered valid training while it was approved. When checking an existing record, check the approval status against the date on the record, not against today.

For what the training must cover, how long it lasts and what the employer has to keep on file, see Working at Heights training requirements in Ontario.

Last verified August 23, 2026 against Ontario's published dataset, which the ministry last updated July 31, 2026. Approval status changes between republications, so confirm against the ministry list before booking.
