Canada's men's relay team, led by star sprinter and 100-metre bronze medallist Andre De Grasse, qualified for the final of the 4x100-metre relay, finishing fifth in their heat, but sixth overall among the two heats.

They will be in lane three for the final, right next to Jamaica.

The Canadian squad, consisting of  De Grasse, Brendon Rodney, Justyn Warner, and Aaron Brown, posted a time of 38.03 seconds.

Jamaica, France, China, Antigua & Barbuda finished ahead of Canada in their heat, qualifying for the finals, while the U.S. Great Britain & Northern Ireland, and Germany round out the competition going for gold. 

Usain Bolt, who won the 100-200 sprint double, didn't run for the Jamaican team that won the second heat in 37.41 seconds. 

However, he is expected to run for Jamaica in the final, where they will undoubtedly have their hands full with the U.S., led by Justin Gatlin.

Gatlin, who has two silver medals in the first two meetings with the Jamaican, has been feeling the effects of all this racing.

"I hope he's tired, too," Gatlin said.
