The 2021 Canadian Tire National Skating Championships were scheduled be held on February 8–14, 2021 at the Doug Mitchell Thunderbird Sports Centre in Vancouver, British Columbia. Medals were to be awarded in the disciplines of men's singles, women's singles, pair skating, and ice dance on the senior and junior levels. Although the official International Skating Union terminology for female skaters in the singles category is ladies, Skate Canada uses women officially. The results were supposed to be part of the Canadian selection criteria for the 2021 World Championships. (The other three ISU Championship events (the 2021 Four Continents Championships, and the 2021 World Junior Championships) were cancelled.)
