The Globe and Mail reports in its Friday edition that BMO has tightened mortgage lending rules for self-employed Canadians in several industries vulnerable to U.S. tariffs. The Globe's Shane Dingman writes that hundreds of thousands of self-employed Canadians working in the steel and aluminum industries, along with nine other "high risk" industries that BMO believes could face a "turbulent economic landscape," will find it tougher to secure attractive lending rates as a result of U.S. President Donald Trump's taxes on Canadian exports. BMO's guidance to external mortgage brokers warns that entire categories of the economy -- construction, transportation, leisure/entertainment, retail sales, banking/finance, manufacturing, farming/natural resources, wholesale trade and utilities -- are on its "Limited" list. Self-employed people in those trades will see tougher qualification rules and less credit extended to them, the bank's memo says. "To broad-brush it like that, it boggles my mind. Especially now when we're all feeling Canadian and very proud," said mortgage broker Trevor Daly. The likely impact of BMO's change will be to shrink the size of a mortgage available to self-employed Canadians in the affected industries.
