Nationwide Tour leading money winner Tripp Isenhour, Mario Tiziani, Travis Perkins and Mike Perez are knotted in second place at 6-under-par 66.
Turcott, a Canadian Tour player who is making his first start on the Nationwide Tour this season, collected his first birdie of the round at the second, then ran off back-to-back birdies from the fourth. He added a birdie at the par-3 eighth to make the turn at 4-under 32.
On the back nine, Turcott parred his first three holes, then posted two birdies in a row from the 13th. He closed with back-to-back birdies to grab the first-round lead.
All totaled, none of Turcott's birdie putts were longer than 10 feet. Six came from the 15- to 18-foot range, and he found 10 of 14 fairways en route to his 64.
'I felt good on the range and felt like it was going where I wanted it to go,' said Turcott. 'I started rolling it pretty well and had a lot of good chances. You're going to have some downhill putts out here. You play a little more break with less speed and let it work its way in there. My speed was pretty good today.'
This has been a remarkable week for Turcott. He was married last Saturday, then had a lesson the next morning with his coach, Dennis Tiziani, the father of Mario, who shares second place.
Then, on Monday, Turcott shot a 66 in the open qualifier to earn his spot in the field. If he failed Monday to qualify for this event, Turcott and new bride Christie, were going to drive 11 hours to this week's Canadian Tour event, the MTS Classic in Winnipeg.
'I got a case of the Mondays and for once it was a good Monday,' said Turcott, who is making only his third career start. 'We'll take it one day at a time. It's been my dream to play out here ever since I was little. You've got to follow your dreams I guess.'
Tim O'Neal, Brent Schwarzrock, Cliff Kresge, Stiles Mitchell, Jin Park, Tommy Tolles, Jeff Quinney and Steve Schneiter are tied for sixth place at 5-under-par 67.
