The Canadian sprinter secured men's 200 metres silver at Rio 2016 behind the now-retired Jamaican great Usain Bolt.

De Grasse also won bronze over 100m behind Bolt and the United States' Justin Gatlin, before leading Canada to the same medal in the men's 4x100m relay.

The 25-year-old suffered two hamstring injuries in the following years, which ruled him out of both the 2017 World Athletics Championships in London and the Gold Coast 2018 Commonwealth Games.

De Grasse impressed at last year's World Athletics Championships in Doha, where he earned 200m silver and 100m bronze.

The Canadian told The Sports Network that he was aiming to lower his personal bests, which he believes will give him an opportunity for gold at the re-arranged Olympic Games in Tokyo next year.

"I've had experience with winning bronze and silver at the biggest stage, and I want to give myself an opportunity to win a gold medal," De Grasse said.

"My first goal is just to run fast and have a personal best.

"Then it's to try to break the Canadian record and, in the process, try to win a gold medal.

"Those are my main objectives."

De Grasse's personal best over the 100m was set at the World Athletics Championships last year, where he clocked 9.90.

His 200m personal best remains the 19.80 achieved at Rio 2016, with the mark also a Canadian record.
