Calls are growing from within the Liberal caucus for Prime Minister Justin Trudeau to step down as party leader — and some have pegged Chrystia Freeland as their choice to replace him.Twenty-one Liberal MPs have publicly urged Trudeau to resign — many of them within the last week — after Freeland shocked Canadians on Monday by resigning as deputy prime minister and finance minister hours before she was supposed to table the government's fall economic statement.

The news shocked cabinet and caucus colleagues, senior Finance Department officials and the Prime Minister’s Office, and caused chaos among the Liberal ranks.

Prime Minister Justin Trudeau’s hold on power was threatened on Monday after the deputy prime minister who led Canada’s response to the first Trump administration resigned abruptly, in a stinging rebuke to the country’s leader.
