Good morning!

Here's your daily dose of five things to know: Unifor and General Motors Canada reach a last-minute tentative agreement, averting strike action; Prime Minister Justin Trudeau will address the UN General Assembly this afternoon; the UN humanitarian aid agency suspends aid convoys in Syria after a deadly attack; Canadian researchers say they’re on the verge of a new era of unhackable internet communication; and Jim Carrey public defends himself after he was named in a lawsuit for the wrongful death of his ex-girlfriend.

1. Deal reached: General Motors of Canada and the union representing 4,000 of its workers reached a tentative agreement early this morning. The deal has ended speculation that GM would shut down its assembly plant in Oshawa, Ont.

2. Trudeau at the United Nation: Prime Minister Justin Trudeau will address the UN General Assembly in New York City this afternoon. On Monday, Trudeau announced $64.5 million in multi-year funding to support people affected by humanitarian crises around the world.

3. Aid suspended: The UN humanitarian aid agency is temporarily suspending all convoys in Syria after an airstrike on aid trucks killed 12 people, mostly drivers and Red Crescent workers. A ceasefire in the war-torn country is in jeopardy following several violations in recent days.

4. No more hacking: Canadian researchers have announced new quantum teleportation distance records, which they say could usher in a new era of unhackable internet communication.

5. Jim Carrey: Canadian-born actor and comedian Jim Carrey says a wrongful death lawsuit filed by the estranged husband of his ex-girlfriend is a “heartless” attempt to exploit him. Mark Burton has sued Carrey, accusing the actor of providing the prescription drugs his wife Cathriona White used to overdose last year.
