The PGA Tour continues its trek in the Great White North for the final event before the third major championship of the season. The 2025 RBC Canadian Open is taking center stage with the nation's championship being contested at its 38th different host venue in tournament history as the North Course at TPC Toronto welcomes players for 36 more holes.

McIlroy turned in 5-over 40 and then started his back nine in bogey-double-par-bogey. In danger of shooting in the 80s, he played his final four holes in 1 under. The 78 was McIlroy’s worst score since shooting the same number in the first round of last year’s Open Championship.
