A level-par 72 means Graeme McDowell will miss the cut at the Canadian Open.
He was left on three over and five shots outside the projected mark.
2010 US Open champion McDowell, who has struggled for form this season, needed a big improvement on his opening 75 to have any chance of making the weekend.
But his hopes were ended early on Friday as a bogey at this third hole was soon followed by a double bogey.
He fought back with four birdies but the damage had already been done.
It has been a tough year for McDowell who has struggled for form, slipping to 58th in the world rankings.
The Portrush man finished joint 49th at the Open last week, 11 shots behind winner Zach Johnson.
Meanwhile, Michael Hoey failed to make the most of an impressive opening round at the European Masters carding a three-over-par 73 in Switzerland.
The Belfast man enjoyed a hole-in-one on the way to a 65 on Thursday but a quadruple bogey and triple bogey contributed to a disappointing round as he finished on two under and 11 shots behind leader Englishman Danny Willett.
