Hello, welcome to Politics Insider. Let’s look at what happened today.
U.S. President Donald Trump says his government will impose 25-per-cent tariffs on Canadian and Mexican goods starting midnight Tuesday, noting there is no room left for either country to make a deal to avoid the punishing levies.
Speaking to reporters at the White House Monday, Trump confirmed the tariffs will go ahead as planned, adding the countries will need to build cars and other items in the United States to escape the duties.
Meanwhile, ahead of an expected federal election this spring, former Conservative prime minister Stephen Harper is accusing Liberal leadership frontrunner Mark Carney of falsely taking credit for managing the 2008 financial crisis. Harper also linked him to increases in the federal deficit and the Trudeau government’s failure to build energy projects.
In a hard-hitting fundraising letter issued today to Conservative Party faithful, Harper said the former central banker is not the right leader to handle U.S. President Donald Trump and his punitive tariffs.
Also today, Canada is getting a new ambassador to Ireland: former Prince Edward Island premier Dennis King.
The PMO announced the appointment today.
King abruptly resigned as premier and Progressive Conservative leader last month, saying the decision was in the best interests of his family, the government and PEI residents.

Perspectives
A reminder, Mr. Ford, that you’re a conservative
Having put Ontario through an unnecessary election, Premier Doug Ford has retained his job and secured a third straight government majority. Time for him to start using that power more wisely.

This is not an argument for mere representation or performative tokenism. The times are too important for anything less than an affirmation of treaty relationships as a first point of defence.

A deal-breaking Donald Trump and his tariff drama
