Here are some things for Canadian fans to keep an eye on:

Track and field: The Canadian men's relay team is back 

Olympic 4x100m champions Andre De Grasse, Aaron Brown, Jerome Blake and Brendon Rodney are competing in the World Athletics Relays in China, their first big event since their stunning victory in Paris last summer.

Last year's World Relays in the Bahamas were a big stepping stone for the boys, who took silver behind the United States and earned an Olympic berth. This time, they'll be trying to secure a spot in the world championships in Tokyo in September.

The top two finishers in each of the four opening-round heats on Saturday at 8:25 a.m. ET get into the worlds and advance to the final on Sunday at 9:26 a.m. ET, where they'll race for the $40,000 US top prize. The other teams go to a second-chance qualifying round on Sunday at 8:32 a.m. ET, where the top two in each of the three heats receive a spot in the worlds.

Canada's opponents include the United States, which is without Olympic and world 100m champion Noah Lyles but will feature back-to-back Olympic 200m silver medallist Kenny Bednarek; Jamaica, led by Olympic 100m runner-up Kishane Thompson; and South Africa, which finished just 0.07 of a second behind Canada to take the silver in Paris.

Canada also has teams in the women's 4x100m and 4x400m after finishing sixth in both events at the Olympics, as well as the mixed 4x100m and 4x400m. The mixed 4x100 event is making its global debut and won't be part of this year's world championships, but it was recently added to the Olympic program for 2028 in Los
