Ontario is home to more than 40 per cent of Canada’s billionaire families while also accounting for the country’s largest share of families living below the poverty line, according to a new report that is renewing calls for a tax on extreme wealth.
The report, released by advocacy group Canadians for Tax Fairness, estimates that 38 billionaire families reside in Ontario, representing the highest concentration in the country. It also states that nearly half of Canada’s families with assets exceeding $100 million are based in the province, with the wealthiest 0.01 per cent holding an average net worth of approximately $546 million.
At the same time, nearly 1.9 million Ontario families are estimated to be living below the poverty line, accounting for about 40 per cent of all low-income families in Canada. The report argues that the growing gap between the richest and poorest households warrants new measures to redistribute wealth and fund public services.
Canadians for Tax Fairness is proposing that Ontario introduce a wealth tax targeting the ultra-rich, saying revenues could be used to support health care, education and other social programs. Depending on the tax structure, the group estimates the province could raise billions of dollars annually through taxes ranging from one to five per cent on fortunes exceeding $10 million.
Supporters of wealth taxes argue that Canada’s tax system disproportionately benefits wealthy individuals, many of whom can use tax planning strategies and offshore arrangements to reduce their tax burden. Anti-poverty organizations have also called for stronger measures to address growing wealth inequality.
However, critics warn that wealth taxes are difficult to administer and could discourage investment. University of Toronto economist Joseph Steinberg argues that taxing large fortunes may reduce economic activity and encourage wealthy individuals and businesses to relocate to jurisdictions with lower taxes. He cautions that provincial wealth taxes are particularly risky because high-net-worth individuals are highly mobile and can move assets or residences more easily.
To address these concerns, Canadians for Tax Fairness has suggested measures such as an exit tax to discourage wealthy individuals from moving assets out of the province, as well as the possibility of a one-time wealth levy.
Similar debates are taking place elsewhere. Massachusetts has already implemented higher taxes on high-income earners, Washington State is considering additional levies on wealthy residents, and California voters are expected to decide on a proposed billionaire tax later this year.
The report has added fuel to a broader discussion over how governments should address rising inequality and whether greater taxation of extreme wealth could help finance public priorities without harming economic growth.
The issue remains highly divisive, with supporters viewing a wealth tax as a tool to create a fairer society, while opponents warn that it could ultimately weaken investment and drive capital elsewhere.
