Notices of Change

What is a Notice of Change?

Under section 9.3 (1) of the Condominium Act, 1998 (the “Condo Act”), all condominium corporations are legally required to file a notice of change (NOC) with the Condominium Authority of Ontario (CAO) when certain information filed in a condo return has changed or needs to be corrected. The requirement to file NOCs is set out in Ontario Regulation 377/17.

When filing a NOC, condo corporations will indicate what information has changed or is being corrected, and if required, when the change(s) took effect. NOCs must be filed online, using the CAO’s user-friendly filing system. If you have questions, please refer to the CAO’s helpful filing guide which can be accessed through the link below:
