The Globe and Mail reports in its Tuesday edition that some of Canada's biggest bank chief executive officers have jumped into the discussion on how the country and the financial sector could mitigate the effects of tariffs, should U.S. President Donald Trump proceed with his threatened 25-per-cent tariffs on Canada and Mexico. The Globe's Stefanie Marotta writes that CIBC boss Victor Dodig supports the federal government agreeing to appoint a "border czar," as well as offer financial support for businesses affected by the trade war. National Bank's Laurent Ferreira urged Ottawa to relax regulatory and tax burdens and implement its own reforms -- including a "Buy Canada Act." Royal Bank of Canada is in discussions with Ottawa to develop programs and resources that could help its clients navigate the economic effects of a trade war. During the pandemic, Canada's banking regulator lowered capital reserve requirements for large banks by cutting the domestic stability buffer. The federal government also provided financial support through payment deferral programs. For years, economists have been urging the federal government to increase trade with other countries and reduce Canada's reliance on the U.S. market.
