Canadian Open (tennis)

The Canadian Open (French: Tournoi de tennis du Canada, currently branded in English as the National Bank Open presented by Rogers for sponsorship reasons and in French as the Omnium Banque Nationale présenté par Rogers) is an annual professional tennis tournament held in Montréal and Toronto, Canada. It is played on outdoor hardcourts. The men's competition is an ATP 1000 event on the ATP Tour, and the women's competition is a WTA 1000 event on the WTA Tour. It is the second-oldest active tennis tournament in the world, after Wimbledon.

Prior to 2011, the two competitions were held during separate weeks in the July–August period; now the two competitions are held during the same week in August. The men's and women's tournaments alternate host cities on an annual basis; since 2021, Sobeys Stadium in Toronto and IGA Stadium have hosted the men's tournament in odd- and even-numbered years respectively, with the other city hosting the women's tournament.

The most recent Canadian men's player to win the singles title was Robert Bédard who won the last of his three Canadian Open singles championships in 1958. The most recent Canadian women's player to win the singles title was Victoria Mboko in 2025.
