Filing Requirements

File a Return

All condominium corporations are legally required to file condo returns with the Condominium Authority of Ontario. Returns can be broken down into four categories depending on the date the condo corporation was created. 


  • Condo corporations must file returns with the Condominium Authority of Ontario
  • Corporations must pay penalties for late filings
