Canada picked up its fifth Olympic medal in the pool in the women's 200-metre backstroke.
Kylie Masse's Canadian-record time of 2:05.42 was only surpassed by Australian Kaylee McKeown in Tokyo.
Masse was leading through the first three laps, but McKeown's final charge gave the Australian the gold. Her time was 2:04.68.
Veteran Australian Emily Seebohm captured bronze and Canadian Taylor Ruck, who was born in Kelowna, came sixth.
McKeown also won gold and Masse won silver in the earlier 100-metre backstroke at the Tokyo Games.
Meanwhile, Canadian sprinter Andre De Grasse cruised to victory in his first 100-metre heat, finishing in a time of 9.91 seconds.
Another Canadian highlight came in women's soccer, with the Canadian team defeating Brazil in penalty kicks to move to the semi-finals.
