The 2026 RBC Canadian Open at TPC Toronto at Osprey Valley enters its final round with a tightly bunched leaderboard after 54 holes, where Jackson Suber leads at 13 under, followed closely by Bud Cauley at 12 under and a group at 11 under that includes Wyndham Clark, Tommy Fleetwood, Brice Garnett, and Jesper Svensson. Multiple players sit within striking distance of the top 20, amplifying movement potential in the closing round. Possible inclement weather has prompted adjusted tee times in threesomes off split tees, which could compress the schedule and introduce variable playing conditions. A strong international field featuring players such as Matt Fitzpatrick, Viktor Hovland, Shane Lowry, and Robert MacIntyre adds depth, while several Canadians including Taylor Pendrith and Sudarshan Yellamaraju remain in contention. Recent scoring trends and positioning relative to the projected cut line will heavily influence which golfers secure or maintain a top-20 finish.
