"While the lowest five corporate tax rates worldwide are held by corporate tax havens (led by Ireland), the United States and Canada have ranked ninth and tenth respectively out of 33 major economies for the past two years. The corporate tax rate in Canada is lower than all the averages of regional jurisdictions, including the global and G7, according to the average tax rates of 33 UHY international firms, assuming companies have a profit of $1 million. "
Canada's problem is not excessive taxation. It's monopolies and lack of competition and over-reliance on commodity exports.
