Tour Challenge

The Tour Challenge, known as the HearingLife Tour Challenge for sponsorship reasons, is a bonspiel, or curling tournament, which is one of the Grand Slam of Curling events. It was introduced into the Grand Slam lineup starting in the 2015–16 curling season.

The event features a men's and women's draw, and is split into two tiers of 16 teams each, Tier 1 and Tier 2.

Since 2022, the format consists of four pools, where each team plays all four of their games against the four teams of another pool. The top 8 teams overall make the playoffs. Beginning in 2023, there are no tiebreakers.

The top 16 teams on the World Curling Federation team ranking qualify for the Tier 1 event, while the next top 16 teams qualify for the Tier 2 event. The winning team at the Tier 2 event qualifies for another Grand Slam, the Canadian Open.
