The 2019 BOOST National was held from December 10 to 15, at the Conception Bay South Arena in Conception Bay South, Newfoundland and Labrador.

In the women's final, Team Anna Hasselborg also won their second consecutive Grand Slam event, defeating Team Jennifer Jones 7–3.

The top 14 men's and women's teams on the World Curling Tour order of merit standings as of November 5, 2019 qualified for the event.

The Grand Slam of Curling may fill one spot in each division as a sponsor's exemption.

The sponsor's exemption was not used, and the spot was allocated to the highest-ranked remaining team on the order of merit.
