The logistical difficulties of travel restrictions and quarantine measures led to the decision to cancel the June 10-13 tournament, which was to be played a week before the US Open.

The event, which had been scheduled at St George's Golf and Country Club in Toronto, is the only Canadian stop on the PGA Tour.

"Even with an extensive health and safety plan in place, we faced a number of significant logistical challenges that led us to this decision," PGA Tour President Tyler Dennis said in a statement.

The PGA Tour will fill the gap by playing a one-off event in the US.

Last year's Canadian Open was also cancelled amid the pandemic. Rory McIlroy won it in 2019.
