2018 National

The 2018 BOOST National was held from December 11 to 16 at the Conception Bay South Arena in Conception Bay South, Newfoundland and Labrador. This will be the fourth Grand Slam and second major of the 2018–19 curling season.

The first all-Scottish Grand Slam final saw Ross Paterson of Glasgow beat defending champions Bruce Mouat of Edinburgh 4–3 in an extra end to win his team's first Grand Slam. Rachel Homan beat Kerri Einarson 4–1 in the women's final, to win her ninth slam.

The event was sold out all week, owing to the popularity of the hometown Brad Gushue rink. The total attendance was 23,500 which was a Grand Slam record at the time.

Qualification
The top 14 men's and women's teams on the World Curling Tour order of merit standing as of November 5, 2018 qualified for the event. The Grand Slam of Curling may fill one spot in each division as a sponsor's exemption. In the event that a team declines its invitation, the next-ranked team on the order of merit is invited until the field is complete. The sponsor's exemption was not used, and the spot was allocated to the highest-ranked remaining team on the order of merit.
