"Paul Martin, closed access to all tax havens for Canadian tax-dodgers save one: the Barbados. The following year, his own Canada Steamship Lines (CSL) promptly moved their operations to the Barbados: CSL has nine shell companies in the Barbados, all sharing one mailbox. Bypassing Canadian taxes, about 1700 Canadian companies have set up affiliates to take advantage of the Barbados’ 2.5% tax rate. In 2000 alone, these companies, which bring their profits into Canada without paying Canadian tax, imported $1.5 billion dollars into Canada, resulting in a tax revenue loss of $345 million (based on 2003 corporate tax rate of 23%)."
