What are Condo Returns?

Under section 9.2 (1) of the Condominium Act, 1998 (the “Condo Act”), all condominium corporations are legally required to file condo returns with the Condominium Authority of Ontario (CAO). Filing a condo return means providing the CAO with specific information about the condominium corporation, such as the date it was registered, its address for service, and information about the current board of directors (“the condominium board”).

What is a Notice of Change?

Under section 9.3 (1) of the Condo Act, all condo corporations are legally required to file a notice of change (NOC) with the CAO when certain information filed in a condo return has changed or needs to be corrected. An NOC must be filed within 30 days of the change indicating what has changed and when the change took effect.
