"A once in a generation moment" for Europe's security. That is how Britain's Prime Minister Kier Starmer is framing Sunday's summit, aimed at achieving peace in Ukraine. In attendance was Justin Trudeau along with the leaders of more than a dozen European countries. The summit was planned some time ago, but it's taking on added significance after Friday's tense meeting between Donald Trump and Volodymyr Zelenskyy.

Also: The White House is again sending mixed signals about its threatened tariffs. The U-S seems poised to impose the sweeping measure this Tuesday. But it's still unclear, if those tariffs will be as steep as originally planned.

And: Around this time next Sunday, the Liberal Party will elect its new leader. Voting is already underway, but a voting app that was supposed to make the process simpler and more secure is now causing issues.
