The results are pretty good after round one.
Parnevik shot a 4-under-par 67 to finish two-shots off the lead at the Northview Golf & Country Club in Surrey, BC.
Its not all good news, however, as the 36-year-old Swede finished his round with back-to-back bogeys.
I got a little bit tired at the end and lost a little bit of my focus, Parnevik said. It was a bit of a sloppy finish.
Greg Kraft and Joel Edwards are tied for first place following a pair of 6-under 65s. Brent Geiberger (66) and Chris Riley (66) are one back. Defending champion Rory Sabbatini is among the 12 players tied for fifth place at 4-under.
Parnevik, who is expected to be a captains selection for the upcoming Ryder Cup, is trying to regain the form that led him to a victory in this years Honda Classic.
Parnevik has missed only one cut in his last 11 starts on the PGA Tour, but has only recorded two top-10s in that same time span.
Thursday, the five-time tour winner birdied five of his first six holes. He made his way to the top of the leaderboard at 6-under through 16 holes, but bogeyed Nos. 8 and 9 ' his final two holes of the day.
Parnevik is currently 30th on the PGA Tour money list, with the top-30 qualifying for the season-ending Tour Championship.
Meanwhile, Kraft and Edwards are battling to keep their cards.
Kraft is 112th in earnings, while Edwards is a more comfortable 99th.
Kraft started his day with a bogey at the 1st, but recovered to notch eight birdies to just one more bogey over his final 17 holes.
Its been a while, so Im enjoying it very much, said Kraft, who won the 1993 Deposit Guaranty Golf Classic, though it was not an official tour event at the time.
Its been tough all year, one of the toughest years Ive had.
Edwards is also in search of his first tour title. He finished tied for second in the 1992 B.C. Open.
I did everything well today and I kept my head together, which is pretty rare for me, said Edwards.
Erik Compton, making his professional debut this week, shot 3-under 68. Fellow first-timers James Driscoll and Jeff Quinney opened in 1-under and 2-over, respectively.
Mike Weir, the 1999 Air Canada champion, shot 2-over 73. He is, at 12th in the Official World Golf Ranking, the highest ranked player in this weeks field.
It was a frustrating round and I didnt play very well, Weir said. Ive had poor first rounds before and come back so I can draw upon that and hopefully, I can come back tomorrow and get myself back in this thing.
