Good morning. Canadians will soon have some access to the enormously popular, U.S.-based prediction markets. We'll get into that below, plus why an unlikely animal helped stop flooding in the U.K. and the facts behind U.S. President Donald Trump's threats about CUSMA.

Massive drone attack again hits Moscow oil refinery

Ukraine hit a major Moscow oil refinery for a second time in a week and disrupted commercial flights at the capital's airports.

What's happening: Hundreds of drones were launched into Russia — the exact figure is unclear — striking one of the country's biggest oil refineries and other targets in the Moscow area. Sixteen people were injured, according to the regional governor, and Russia retaliated with more missile strikes against Kyiv.

Why it matters: Ukraine has been targeting Russia's oil facilities, aiming to cut Moscow's revenue for the war and make Russians feel the consequences of the invasion. Ukraine President Volodymyr Zelenskyy says he hopes this will force Putin to the negotiating table.

Leave it to the beavers: How the industrious mammals are helping to stop a London tube station from flooding

The work of the industrious beaver may have saved a neighbourhood in London, from routine flooding.
 
What's happening: The U.K. capital got its first beavers in 2022 — a male and female pair named Justin and Sigourney Beaver. Soon after, five more were released into a wetland area called Paradise Fields, near Heathrow Airport. The thinking was that the beavers' dam work would reduce flooding, which in theory would let the local council scrap or scale back planned, expensive engineering work.

How it panned out: It's been two and a half years since the latest beaver push, and project staff say the nearby Greenford tube station hasn't flooded since. There are now proposals to release more beavers in south London. Meanwhile, at the site of the original five beavers, there are now believed to be a total of eight. That includes mother Willow, who — no offence — is a bit of a heavy lady. At 30 kilograms, she holds the title of being the heaviest beaver ever translocated in the U.K.

Trump wants CUSMA to expire 'immediately.' Here's the reality

U.S. President Donald Trump wants the Canada-U.S.-Mexico Agreement to expire immediately. But that's not exactly how it works.

What's happening: Each nation must declare by July 1 whether it wants to extend the trade deal, which covers some $2.7 trillion in annual goods and services trade between the three, beyond its 2036 expiry date. While Trump has said he believes the U.S. would be better off without the deal, there is plenty of evidence it has helped fire up the U.S. economy. For example, 13 million U.S. jobs are supported by trade with Canada and Mexico.

What else: CUSMA also doesn't expire immediately, as Trump may be willing it to, because it took effect in 2020 for a term of 16 years, meaning there is still a decade left. While terminating it is a possibility — it just requires six months' notice — Trump has not yet explicitly threatened to do so. And it's also unclear whether he even has the power to, given U.S. Congress may have to consent to it.
