The Canadian Open (also known as the Canada Masters), currently sponsored as the Rogers Cup, is an annual tennis tournament held in Canada. The men's competition is a Masters 1000 event on the Association of Tennis Professionals (ATP) tour. The women's competition is a Premier 5 tournament on the Women's Tennis Association (WTA) tour. The competition is played on hard courts.

The two competitions are currently held during the same week in August. Before 2011, they were held during separate weeks in the July–August period. The events alternate from year-to-year between the cities of Montreal and Toronto. In odd-numbered years, the men's tournament is held in Montréal, while the women's tournament is held in Toronto, and vice-versa in even-numbered years.

He is the only male player in tennis history to have reached the title match of each Grand Slam tournament at least five times and also the final at each of the nine ATP Masters 1000 Tournaments. Many sports analysts, tennis critics, and former and current players consider Federer to be the greatest tennis player of all time.
