Canadian Open: Rules & Regulations

canadian open


The Canadian Open features 16 men’s and 16 women’s teams with a triple knockout bracket format.

Triple Knockout & Playoff Qualification

Teams must win three games before they lose three in order to advance to the playoff round.

All 16 teams start in the A brackets. Winners stay in A while losers drop to the B brackets.

The winners in B remain in that bracket while the losers fall to the C brackets.

The C brackets are the last chance for teams to qualify for the playoffs and once a team loses in the C brackets they are eliminated from the tournament.

Two A teams (3-0), three B teams (3-1), and three C teams (3-2) advance to the playoffs.

Rules of Play

All matches will be contested under the Curling Canada “Rules of Curling for Officiated Play.”

Five-rock rule

All games in the Pinty’s Grand Slam of Curling are played utilizing the five-rock rule.

Teams must wait until five rocks have been played before they can start eliminating rocks that are sitting in the free-guard zone (outside the house from the tee line to the near hog line). The five-rock rule is designed to generate more offence with an extra guard in play.


All matches will be eight ends. Teams have 33 minutes and two (2) x 90-second timeouts using the “Slam Time” System.

Slam Time

Teams are allowed a maximum of 30 seconds to deliver the first rock of an end. If the delivering team has not delivered its first rock within the 30 seconds, their clock will start. (Applicable at Head Official’s discretion)

If a team runs out of time, they will stop delivering stones for the rest of the eight-end match.

Please note that this rule will be enforced. It is your responsibility to monitor your clock. The head official may notify a team if he deems it necessary.

Extra End

Teams get five minutes to complete an extra end regardless of how much time they finished the eighth end. Each team gets one (1) x 90-second timeout regardless of how many timeouts they had remaining after the eighth end. If a team runs out of time in the extra end they will stop delivering stones.

Draw to the Button

During this event, any team member may execute the draw to the button. The chosen player will first deliver a rock towards the home end with the help of brushers. If the player covers the pinhole completely, the same shooter will then deliver a second draw to the button without brushers. Should both teams cover again, a third stone would be delivered by a different player with the help of one brusher only, then no brusher if both teams cover again and so on until we determine a pre-game draw winner.

Entry Fee & Purse Breakdown

Entry is $1,200.00 per team. Entry fee will be deducted from winnings for all teams.

A $125,000 (CDN) purse is on the line in both men’s and women’s divisions.
