All four of Canada's individual track and field medallists from the Tokyo Olympics have opportunities to win medals this weekend at the World Athletics Championships in Oregon. Plus, a talented youngster who struggled in Tokyo looks ready to make a run at the podium. Here are the Canadians to watch on Friday night, Saturday and Sunday as the worlds come to a close:

Andre De Grasse (men's 4x100m relay)

By winning gold in the 200m and bronze in the 100m at the Tokyo Olympics, De Grasse extended his medal run in individual events at major championships to an incredible seven in a row. The streak ended last weekend when the 27-year-old, who was coming off a bout with COVID-19, failed to advance past the semifinals of the 100m at worlds. De Grasse then skipped his best race, the 200m, in order to rest up for the 4x100, which begins with the heats tonight at 9:05 p.m. ET.

Canada's lineup tonight will be the same as the one that took Olympic bronze (later upgraded to silver) last summer: Aaron Brown, Jerome Blake, Brendon Rodney and De Grasse. The final is Saturday at 10:50 p.m. ET.

Despite 100m champion Fred Kerley being out with a leg injury suffered in the 200m semifinals, the United States will be tough to beat because of its unmatched depth. Marvin Bracy and Trayvon Bromell took silver and bronze in the 100m last weekend, and 2019 world champ Christian Coleman was sixth. 200m gold medallist Noah Lyles and bronze winner Erriyon Knighton are also candidates to run the 4x100 relay.

Canada also has a team in the women's 4x100m heats at 8:40 p.m. ET, but it's not considered a medal
