Ontario is participating in a Joint Task Group to investigate provisions to allow expanded use of EMTC. British Columbia and Quebec are leading an initiative where one or more provinces amend their building codes with the same code provisions in advance of the National Construction Codes. Unlike the established Code harmonization process that Ontario has committed to, where the National Construction Codes change first and provincial codes follow, provinces that amend their codes with these proposed changes would be aligned with each other, with the expectation that the National Construction Codes will adopt the same changes in the future. No decisions have been finalized about whether Ontario will adopt changes based on these proposals.

OAA President, Settimo Vilardi, writes to the Canadian Board for Harmonized Construction Codes (CBHCC), in response to the ongoing consultation on harmonization of the Ontario Building Code with the National Codes. The OAA remains steadfast in its position that energy efficiency should remain a key piece of the harmonization process.
