The Globe and Mail reports in its Wednesday edition that upheaval in Canada's federal government is causing greater uncertainty for businesses, while Donald Trump's return to government also brings risks to the banks' clients, with the incoming U.S. president threatening sweeping tariffs on Canada. The Globe's Stefanie Marotta writes that the country's largest lenders face mounting global political uncertainty, rising mortgage competition and intensifying anti-money-laundering requirements. The unravelling of Prime Minister Justin Trudeau's Liberal government has been added to the list of banking risks. Banks are also facing mounting scrutiny over their defences against financial crime. Early last year, a U.S. banking regulator ordered RBC's U.S.-based subsidiary City National Bank to implement reforms for gaps in many of its internal controls and risk-management processes. In October, TD Bank pleaded guilty to conspiracy to commit money-laundering, prompting a suite of severe penalties from U.S. regulators and law enforcement, including a $3-billion (U.S.) fine. TD chief operating officer Raymond Chun said the bank is considering several options, including a sale of its 10.1-per-cent share of Charles Schwab Corp.
