As Canadians cast their ballots in a pivotal federal election today, U.S. President Donald Trump has reignited controversy by suggesting that Canada should become the 51st state of the United States. Polling stations opened at 7:00 a.m. local time (7:30 p.m. IST) and will close at 9:30 p.m. (10:00 a.m. IST Tuesday), with early voting already surpassing 7 million ballots.
