The 2021 Canadian Open (branded as the 2021 National Bank Open presented by Rogers for sponsorship reasons) were outdoor hard court tennis tournaments played from August 6 to August 15, 2021, as part of the 2021 US Open Series. The men's event took place at the Aviva Centre in Toronto, and the women's tournament at the IGA Stadium in Montreal. It was the 131st edition of the men's tournament—a Masters 1000 tournament on the 2021 ATP Tour, and the 119th edition of the women's tournament—a WTA 1000 tournament on the 2021 WTA Tour.[1][2]
They were originally scheduled to be played from August 8 to August 16, 2020, as part of the 2020 tennis season. Due to the COVID-19 pandemic, the 2020 edition of the Canadian Open was postponed to 2021 by Tennis Canada.
