In 2015, it was discovered that 1859 individuals linked to Canada, including a number of prominent billionaires, had secretly been keeping money in HSBC’s Swiss private bank, presumably in some cases to avoid the payment of Canadian income taxes.

What is the best way to deal with Canadians who use private banks to hide money for the purpose of evading taxes?
