The third round was suspended due to darkness as the tournament struggles to get back into position. There were eight hours worth of delays on Friday, so the second round was completed Saturday.
The third round will resume at 7:30 a.m. (ET) Sunday morning and the groups will go back out right away without being re-paired for the final round.
Harris and Habig are through four and five holes, respectively. Harris, the Canadian Tour's leading money winner, was 2-over par on his third round, while Habig is even.
David Mathis was 1 over in the third round and is alone in third at minus-7. Ken Duke is 1 under so far in round three and has sole possession of fourth place at 6-under par.
Harris hopes to continue his strong play of late. He has won five titles in the last two months, including the Canadian Players Championship. Harris even tied for 21st last week at the Canadian Open on the PGA Tour.
'To shoot a couple under each day is the goal,' said Harris. 'Mother Nature came out and made things a little sloppy, but that's the way it goes. I'm looking forward to Sunday.'
Habig fired a 7-under 65 in Saturday's second round to get into the championship.
Michael Walton is even through five holes and is in fifth at minus-4.
Brian Unk, Jesse Smith, Jon Turcott and Brock Mackenzie share sixth at 3 under par.
The 36-hole cut came at plus-3 and 41 players will stick around for the final two rounds.
