Doeden shares first place with Lee Williamson, who posted a 70 in round three. Jason Hartwick, who led after each of the first two rounds, managed an even-par 72. He stands at minus-7 and is alone in third.
Jim Lemon shot 70 to move into fourth place at 6-under-par 210. George Bradford, Steve Friesen and Darren Griff are one stroke further back at minus- 5.
Doeden was fortunate to get up and down for par on the first at Hazelmere Golf Club. At the next, he drained 45-foot birdie effort to get off to a flying start.
Later, Doeden birdied the seventh for the third day in a row. He ran off three straight birdies from the 10th, but gave a stroke back with a bogey on No. 15.
'It's a good position to be in,' Doeden admitted. 'That was my goal coming into this year - to get myself in contention as many times as possible.'
Williamson's round of 70 was buoyed by a lucky break at the 10th. His tee ball was sailing towards the out of bounds, but caught a tree and wound up in a bunker. From there, Williamson managed to save par.
On the front nine, Williamson carded three birdies. He also notched birdies on 13 and 15, but faltered with bogeys on 14, 16 and 17 to share the lead.
'I'm a little hot right now, but I'll cool down. If I can execute better and take advantage of my chances, I should be fine,' Williamson admitted. 'I'm tied for the lead. I can't be too disappointed.'
Clint Jensen is alone in eighth place at 4-under-par 212 with Brian Guetz and Josh Habig one stroke back at minus-3. Seven more players are at 2-under-par 214.
