Home favourite Mike Weir and Americans Anthony Kim and Eric Axley fired six-under 65s to share the early first-round lead at the Canadian Open.
Trying to become the first Canadian to lift the title since Pat Fletcher 54 years ago, Weir got his bid off to a bogey-free start at a soggy Glen Abbey course.
Left-hander Weir, who narrowly failed to win the trophy in 2004 when he lost to Fiji's Vijay Singh in a playoff, rolled in a five-footer on his final hole.
Axley went one better, eagling the par-five 18th to end his round just before play was suspended due to bad weather.
Kim, chasing his third title of the season, mixed seven birdies with a single bogey. Lurking two shots back were JP Hayes, Nicholas Thompson and Ryan Armour and Richard Johnson.
