"I think I slipped out of the blocks a little bit, so I just gotta go back and work on that a little bit coming into the semifinals," De Grasse said. 

"But I didn't panic. I knew going home I could just rely on my top end, but in the semifinals I can't do that so I just gotta tighten it up."

Brown also said there were things he needed to improve if he hopes to make the final.

"I have a long schedule ahead of me so I didn't wanna come out guns blazing in the first round. When I saw I was in the top two, I kinda just cruised the last little bit, didn't press it too much," Brown said.

The Canadians will run in the semifinal on Saturday at 11:45 a.m. ET, with the final scheduled for 3:15 p.m. ET. Brown will run in the first heat beside American star Christian Coleman, while De Grasse will run in the second with 2017 world champion Justin Gatlin.

In the first world championships without retired sprint star Usain Bolt since 2003, Coleman maintained his status as the favourite after winning his heat with the day's best time at 9.98. Coleman, 23, was the only sprinter to break the 10-second mark.

Coleman entered the worlds amid some controversy after missing three drug tests within one year, which is supposed to carry the same penalty as a positive result. However, a technicality related to the dates of the missed tests absolved the Atlanta native and allowed him to compete at worlds.
