The Canadian men's 4x100 relay team finished second to the United States in the World Athletic Relays on Sunday.
Brendon Rodney, Aaron Brown, Jerome Blake and Andre De Grasse posted a time of 37.89 seconds behind the Americans in 37.40 in the final. Japan was third in 38.10.
The first 14 of 16 berths for each of the five Olympic relays in Paris were allocated in Nassau.
The Canadian men had already qualified Saturday by winning their heat and posting the third-fastest time.

Toronto's Alyssa Marsh, Kyra Constantine and Zoe Sherar and Aiyanna Stiverne of Laval, Que., placed third in the 4x400.
The group's time was three minutes 27.17 behind the victorious United States in 3:21.70 and runner-up Poland in 3:24.71.
Constantine ran the third leg of the 4x400 in Tokyo where the Canadian women finished fourth and missed the podium by six-tenths of a second.

They didn't reach last year's world championship final in Budapest, Hungary, where De Grasse sat out the heats to save himself for the 200-metre final two hours later. Bolade Ajomale drew in to run the anchor leg.
Canada's mixed and men's 4x400 relay teams needed to finish in the top two in their qualifying heats Sunday to get to Paris, but fell short of that standard.
The mixed relay team just missed by finishing third. The men were fifth.
