Vancouver: Chrystia Freeland, Justin Trudeau's possible successor to be next Canadian prime minister on Monday asserted that Canada needs a "retaliation list" of goods to target if US President Donald Trump makes good on his threat to slap 25 per cent tariffs on Canadian goods,

A list of products worth 200 billion Canadian dollars (USD 139 billion) would send a message to US exporters about the harm tariffs would cause them, Freeland said in a statement.
