Tax evasion, both at home and abroad, is stealing potentially tens of billions of dollars in revenue from federal coffers and ultimately sapping money out of the pockets of law-abiding Canadian taxpayers."People that don't pay their fair share of the taxes means the rest of us have to pay more," says Liberal Sen. Percy Downe, who has been leading the fight in Parliament on tax evasion. "It's a tremendous revenue loss to the country." He wants the government to boost the CRA's funding for fighting tax evasion.
