Canada and its global partners can't keep relying on whistleblowers, snitch lines and investigative journalists to assure the integrity of our tax system. So far, there is little evidence to show that the government has the political will to end this. It is estimated that Canada loses at least $7.8 billion each year from tax haven schemes. The practice hurts both federal and provincial economies. It also undermines public confidence in our tax system. The world of tax havens is a murky one inhabited by the very wily and the cynical.
