In Manitoba, along the longest undefended border in the world, Canadians push back against Trump’s allegations of an “invasion” of migrants and drugs.

Canada’s prime minister said it’s “in the interest of Canadians as well as Americans” to strengthen border security and raised concern about the rising volume of illegal guns and drugs flowing north from the US.

Trudeau made the comment the day after U.S. president Donald Trump threatened again to put 25 per cent tariffs on Canadian and Mexican goods, citing the flow of undocumented migrants and fentanyl across the borders from two of the U.S.’s closest neighbours — and singling Canada out as a “very bad abuser.”
