Erik Compton, who won this year's Central Valley Classic, carded a 67 to join Rob McMillan, Bryan Novoa and Brien Davis in a tie for third place at minus-4.
Baryla collected three birdies over the first nine holes at Mayfair Lakes Golf Club. He added a birdie at the par-5 11th and then birdied the par-4 16th to secure a piece of the opening-round lead.
'The course was playing difficult today, you really have to think your way around,' said Baryla. 'It's a good test of golf. It's been promising for me knowing I can compete week in and week out.'
Carman got off to a quick start with a pair of birdies over his first three holes and added an eagle at the par-5 fifth to reach minus-4.
The 29-year-old faltered to a bogey at the ninth but came back with a birdie at the 11th. Carman added back-to-back birdies from the 13th but gave those shots back with two straight bogeys starting at the 16th.
Carman closed with a birdie at the last to join Baryla in the lead.
Anders Hultman, David Hearn, Brad Fritsch, Duane Bock, Jason Allred, Clint Jensen, Kris Mikkelsen, David Mathis, Will Moore, Michael Sabo and Brian Nosler share seventh place at 3-under-par 68.
Defending champion James Lepp, who became the first amateur to win on the Canadian Tour in seven years when he captured this event last year, managed a 2-over 73 on Thursday.
