The RBC Canadian Open made its debut at the TPC Toronto this year

The RBC Canadian Open is making its first appearance at TPC Toronto, marking a notable change beyond simply testing a new venue for the event. Located in Caledon, about an hour northwest of downtown Toronto, this expansive 54-hole golf facility serves as the official home of the Canadian Open for the foreseeable future.

While the tournament continues to visit well-known parkland courses such as St. George’s and Hamilton, TPC Toronto at Osprey Valley acts as the primary hub for Canada’s national open. The event takes place on the 7,389-yard North Course, formerly known as the Toot, which underwent recent renovations by Canadian designer Ian Andrew to meet championship standards. Golf Canada built its headquarters and library on site, emphasizing the venue’s growing significance.

Tournament director Ryan Paul points to the potential for TPC Toronto to develop a unique atmosphere, distinct from the urban and private club settings typical of recent years. He said via Toronto Sun:

“(TPC Toronto) has established a vibe and an atmosphere and a culture here that is pervasive, and it’s authentically Canadian. It feels different,” he said. “Because it’s a big expanse, it feels a little freer, it’s a little more open … It has that vibe. Lots of water, big trees, that really great feeling.”

Before the tournament, Rory McIlroy acknowledged that while proximity to Toronto offers advantages, the RBC Canadian Open maintains a reputation that allows it to succeed regardless of location.
