Joel Dahmen shot 3-under-par 69 on Friday to maintain his lead at the suspended Celtic Classic.
Dahmen moved to 13-under-par 131 for the tournament before play was suspended due to darkness at the Lakes Golf Club with one group left to finish its second round.
The second round will resume at 6 a.m. ET Saturday and the third round will begin at 7:10 a.m. off the first tee in threesomes.
Dahmen holds a 3-stroke lead over Stephen Gangluff, who shot 68 to reach 10- under-par 134 through 36 holes.
David Skinns shot 68 to move into solo third place at 9-under, one stroke ahead of Mackenzie Hughes (69), Hugo Leon (66) and Ryan Williams (68).
Dahmen held a comfortable lead for much of the day thanks to five birdies and an eagle, although he did trip to a pair of bogeys and closed his round with a double-bogey 6 at the ninth (his 18th).
"Dinner's going to have a little sour taste to it after a double on the last, but I'm hitting it really well and I feel good about my game," said Dahmen. "I'm happy with the way I hit the ball and chipped whenever I did miss a green over the first two days."
NOTES: Dahmen's 3-stroke lead is tied for the largest 36-hole lead on PGA Tour Canada this season ... Dahmen is seeking his first career win on the PGA Tour Canada. He has a pair of top-10 finishes this season ... Brady Schnell is in position to become the only player to make the 36-hole cut in every PGA Tour Canada event this season.
