Mexico has been taking a bashing lately for allegedly serving as a conduit for Chinese parts and products into North America, and officials here are afraid a re-elected Donald Trump or politically struggling Canadian Prime Minister Justin Trudeau could try to leave their country out of the U.

Canada wants Mexico to stay in a continental trade pact despite concerns about China possibly using it as a back door to flood the North American market, a source directly familiar with the matter said on Wednesday.

Trudeau said he would prefer the North American free trade agreement to remain in place, but that Ottawa was 'leaving all doors open' to secure Canadian interests.
