Brad Sutterfield matched Jensen's 67 to climb into third place at 9-under-par 135. First-round leader Lee Curry managed an even-par round of 73. He shares fourth place at 7-under-par 137 with Ben Pettitt, Erik Compton and Jesse Hibler.
Jensen and Higton are both Americans. The winners of the first five Canadian Tour events this season have all been American-born players.
Jensen, who was in the first group out in the morning, had his best finish of the 2003 season at this event when he finished in a tie for third.
'To be the first group out there, when nobody has stepped on the greens, was great,' said Jensen. 'For twelve holes we didn't have to fight the wind. So I think I took advantage of those circumstances.'
Higton played steady throughout the day, posting a bogey-free round.
'I didn't play as well as I did yesterday, but had no bogeys,' Higton said. 'I hit almost every fairway and 14 greens, but I didn't make as many birdies as I wanted.'
Derek Gillespie, the defending champion, carded a 2-under 70 Thursday. He stands in a tie for eighth place at 6-under-par with Conrad Ray, Chris Wall, Brennan Webb, Matt Weibring, Mauricio Molina and Will Moore.
The cut line fell at 1-over-par 145 with 72 players advancing to the weekend.
