Liberal leadership contender Chrystia Freeland released Monday what she's calling her "plan to stand up to Trump" — a policy document that includes the threat of big tariffs on U.S. goods to make the Americans pay if they go after the Canadian economy.

Chrystia Freeland, the former finance minister who is running to replace Justin Trudeau as Canada's prime minister, said Monday Canada needs to release a retaliation list of goods the country would target if US President Donald Trump makes good on his threat to slap 25 per cent tariffs on Canadian goods.

The former finance minister said her plan calls for the immediate release of a long list of $200 billion in retaliatory tariffs to deter Trump from making good on his threat to impose 25 per cent tariffs on Canadian imports as soon as February.

A key candidate running to replace Justin Trudeau as Canada’s prime minister is calling for an international summit to hammer out a joint response to US President Donald Trump’s tariff and sovereignty threats.
