The Ministry of Revenue was the ministry in Ontario, Canada responsible for administering most of the province's major tax statutes as well as a number of tax credit, incentive and benefit programs. The ministry was also responsible for managing relationships, particularly with the Canada Revenue Agency, in their administration of provincial taxes and benefit programs on behalf of Ontario. The ministry promoted the integrity of Ontario's self-assessing tax system by encouraging compliance through taxpayer education and customer service, while discouraging non-compliance through enforcement activities.
Following the 2011 Ontario general election, the Ministry of Revenue was merged into the Ministry of Finance.
