Long tables line the community hall in Round Hill, weighed down by hundreds of items of baking, flowers, crops, crafts and canned goods, all entered by locals hoping to snag a coveted prize ribbon at the Agricultural Society’s annual Bench Show.

But standing by the woodwork he was judging, self-confessed politics junkie Mathew Banack has the area’s imminent federal by-election on his mind. He’s sure Conservative Party Leader Pierre Poilievre will win the Battle River—Crowfoot by-race when he and other voters head to the polls on Monday in Alberta.

Conservative Leader Pierre Poilievre says Prime Minister Mark Carney has broken his promise to deal with U.S. President Donald Trump and find a resolution to the ever-expanding trade war.

Speaking in Calgary Thursday, Mr. Poilievre called the U.S. tariffs on Canadian goods “unjustified and unjustifiable,” and he criticized the Prime Minister for failing to negotiate a deal with Mr. Trump to avoid them.
