On March 29, 2011, the Ontario government filed amendments to Regulation 632/05 (Confined Spaces) that come into force on July 1, 2011.

O. Reg. 95/11 will effectively consolidate regulatory requirements relating to confined spaces from various other regulations into the existing Regulation 632/05, including those applicable to industrial establishments, construction projects, healthcare and residential facilities and mines and mining plants.

The government simultaneously revoked sector-specific confined space regulations in those four areas.

The amendments to Regulation 632/05 maintain the differences between the confined spaces provisions that apply on construction projects and those that apply to other workplaces.

The amendments to Regulation 632/05 were originally proposed on January 7, 2011.
