Australia finished the International Cycling Union (UCI) Track Nations Cup as the leading nation after picking up four gold medals in Milton, including a final day triumph Matthew Richardson.

The 23-year-old World Championships bronze medallist was untouchable in Canada as he faced Jeffrey Hoogland of The Netherlands in the final of the men's sprint at the at the Mattamy National Cycling Centre.

The first race in the best-of-three format saw Richardson take a slim victory with just 0.206 seconds separating the two.

He followed that up with a commanding performance to blow Hoogland out of the water, crossing the line 5.249 seconds ahead of the Dutchman and seal victory.

Britain's double Olympic medallist Jack Carlin got the better of Poland's Mateusz Rudyk for the bronze medal.

Richardson's performance amplified an impressive display from Australia's emerging talents as they finished on the podium five times in five events.

"Today was awesome - one of my favourite days I’ve ever had on my bike," Richardson said.

"I just took confidence in my legs and raced the best way I could.

"The confidence is definitely building.

"There is still more work to be done when I get home but it’s certainly a good start to the season.

"I’ll take my experiences from these two Nations Cups and try and learn as much as possible for Commonwealth Games and the World Championships later this year."

The Australians were unable to double their gold medal tally on the day as Alexandra Manly and Chloe Moran lost out to Italy's Elisa Balsamo and Chiara Consonni in the women's madison by 54 points to 45, while Mia Griffin and Alice Sharpe of Ireland made up the top three on 29 points.

Kelsey Mitchell claimed Canada's only gold medal of the competition after winning the women's keirin with 11.509sec on the clock, pipping World Championships runner-up Mina Sato of Japan and Tokyo 2020 silver medallist Lea Sophie Friedrich to the lead.

Britain's Ethan Hayter took the last gold on offer as he prevailed in the final race of the men's omnium to notch up 163 points overall.

The Tokyo 2020 silver medallist was dominant in the four races, winning three and placing second in another.

The United States' Gavin Hoover and Jan Willem van Schip of The Netherlands came second and third, respectively, with 128 and 125 points.

Athletes are set to head to Cali in Colombia from July 7 to 10 for the third and final Track Nations Cup of the season.
