Serena Williams will compete at the Canadian Open among a host of star-studded names as she ramps up her preparations for the US Open.

Williams returned to Wimbledon in June in what was her first singles match since suffering injury in last year's competition at the All England Club.

The 23-time grand slam champion succumbed to a first-round elimination at SW19, though, falling to Harmony Tan on Centre Court.

While Williams, 40, could offer little assurances she would return to the British major, she suggested she would play at the US Open, stating "there's always motivation to get better and play at home".

Williams will be joined in Canada by world number one Iga Swiatek, four-time grand slam winner Naomi Osaka, French Open finalist Coco Gauff and reigning US Open champion Emma Raducanu as 41 of the top 43-ranked players descend on Toronto, with the tournament starting on August 6.

It will also mark Williams' first appearance at the event since she finished runner-up to Bianca Andreescu in 2019.

"When you read over that star-studded list, it's hard not to get excited about the WTA Tour making its return to Sobeys Stadium," said tournament director Karl Hale.

"Not only is this one of the strongest, if not the strongest, player list we've ever submitted, but it's also the first time in three years that the [Canadian] Open returns to a full capacity.

"We're thrilled that these players will have a chance to play in front of a packed house, and we're even happier for our fans who will get to watch tennis' very best at the 2022 edition."
