About the Ministry

The Ministry of Revenue administers most of the province's major tax statutes as well as a number of tax credit, incentive and benefit programs. The tax revenues collected provide the fiscal foundation upon which many of the government's programs rely. The ministry is also responsible for managing relationships, particularly with the Canada Revenue Agency (CRA) in their administration of provincial taxes and benefit programs on behalf of Ontario.

The ministry promotes the integrity of the province's self-assessing tax system by encouraging compliance through taxpayer education and customer service, while discouraging non-compliance through enforcement activities.
