When you file your taxes in Canada, you file a federal return and (for most provinces) a provincial return at the same time. CRA administers both for most provinces. Quebec is the exception. Ontario residents may receive the Ontario Trillium Benefit, which combines energy, property tax, and sales tax credits. BC residents with lower incomes may receive the BC Climate Action Tax Credit. Several provinces offer credits related to property tax or rent paid - including Manitoba, Ontario, and PEI. Most provinces have a low-income tax reduction or credit that kicks in below a certain income threshold. The best way to find provincial credits is to use NETFILE-certified tax software, which automatically calculates provincial benefits based on your return.
