De Grasse ran the anchor for the finals of the 4 x 100 m relay. Initially in 6th place, De Grasse made an incredible close on Japan and the United States by about 4 metres, though he narrowly missed the bronze medal by 0.02 seconds. Despite this, the Canadians set a new national record of 37.64 seconds, breaking the record set in 1996 in Atlanta. However, the American team that placed third was disqualified for a zone violation (handing over the baton outside of the designated zone) at the first baton change, so the Canadians were awarded the bronze medal.
