Ontario continues trend of uncompetitively high personal income tax rates
THUNDER BAY, ONTARIO ~~~~~ January 5, 2023, (LSNews) Despite promises that provincial personal income tax increases in 2012 and 2013 would be temporary, successive governments have kept them in place for a decade, finds a new study released today by the Fraser Institute, an independent, nonpartisan Canadian public policy think-tank.
“The recent history of personal income tax rates in Ontario is that tax increases governments promised would be temporary ended up being permanent,” said Ben Eisen, senior fellow at the Fraser Institute and co-author of Broken Promises: The persistence of elevated personal and corporate income taxes in Ontario.

That is the finding of a new study published by the Fraser Institute today.
Combined with federal increases, Ontario’s top income tax rate has increased by 7.12 percentage points and is now the third highest top combined federal / provincial-state personal income tax rate in Canada or the United States!
As a result of both federal and provincial tax hikes, Ontario now has the third highest top combined federal/provincial-state personal income tax rate in Canada or the United States—having jumped from 46.41 per cent in 2012 to 53.53 per cent. Combined with federal increases, Ontario’s top income tax rate has increased by 7.12 percentage points.
“Contrary to their repeated promises not to increase taxes, Dalton McGuinty’s government enacted tax increases that raised the province’s top personal income tax rate, also promising the increase was temporary and would later be reversed—neither he nor his successor Premier Wynne made good on this commitment, just as the current Ontario government has failed to take any action,” Eisen said.
The current government has also failed to deliver on promises to go beyond simply undoing previous tax increases and actually reduce the tax burden on Ontarians. When running for office in 2018, the Ford government promised to reduce Ontario’s general corporate income tax rate, but failed to deliver on this commitment.
“The crux of Ontario’s personal and corporate income tax rates history is one of broken promises: governments keep promising to meaningfully reduce taxes on
Summary
- Since 2012, Ontario’s top marginal personal income tax rate (PIT) rate has increased by 7.12 percentage points, from 46.41 to 53.53 percent. As a result, Ontario now has the third highest top combined federal/provincial or federal/ state top income tax rate in Canada or the United States.
- This increase has been the result of both federal and provincial tax increases.
- Despite repeated promises not to increase taxes, Dalton McGuinty’s government (2003- 2013) enacted provincial tax increases that raised the province’s top PIT. Premier McGuinty also promised the increase was temporary and would later be reversed but neither he nor his successor Premier Wynne (2013-2018) made good on this commitment.
- The Ford government criticized its predecessors for maintaining an uncompetitively high PIT rate in Ontario while in opposition, but has also failed to take action to reduce the rate.
- When running for office in 2018, the Ford government promised to reduce Ontario’s general corporate income tax (CIT) rate by one percentage point, but that promise has not been kept.
- High personal and corporate income tax rates reduce economic output over time. As such, the repeated broken promises from different premiers of different political stripes that have contributed to the persistence of high taxes in Ontario have harmed economic growth in the province.
