Canada's Christine Sinclair is closing the book on a glittering international career as the world's all-time leading goalscorer but the country's long-time talisman said one of her greatest triumphs was being a vocal advocate for the women's game.

The 40-year-old, who has 190 goals in 327 appearances, announced her retirement from the Canada team on Friday but plans to play for the NWSL's Portland Thorns next season.

Portugal's Cristiano Ronaldo hold the men's international scoring record with 127 goals.

Sinclair, who won an Olympic gold medal and appeared in six World Cup tournaments, says she is leaving the international stage in an immeasurably better place than she found it.

"One of the things I'm most proud of is the growth of the game and then, here in Canada, the fight for pay equity and standards," Sinclair told Reuters in an interview.

"When I first joined the national team as a 16-year-old, it's not that you don't care, but you have other things to worry about. You're just happy to be there.

"Just knowing that the team and the sport is in a better place than when I joined the national team ... and the fight is not over. I will still continue to fight for this team and the players, pro league, I feel like as women that will be a never- ending battle and it's one that I will continue to fight."

THRILLING TRIUMPH

Sinclair said she knew Canada's thrilling triumph in Tokyo was her final Olympics in 2021. She stuck around in the hope of helping Canada capture an elusive World Cup medal but it was not to be, their elimination coming in a 4-0 thrashing by hosts Australia in their final group game.

"I knew it was coming to an end just based on what I wanted to do in terms of a timeline. And then, I couldn't have that Australia game the last game I played for Canada," she said. "So, it was important to be part of the group trying to qualify for Paris, to go out on a better note than the World Cup."

Canada clinched their Paris Olympics berth with a September 26th win over Jamaica in Toronto. Cameras caught a teary-eyed Sinclair embracing teammates. She informed coach Bev Priestman that night of her decision to retire.

"I still get excited to go to training. I still have an off day and I'm like, 'What can I do in terms of it not being an off day?' I think I'm always going to be wired like that," she said.

"But what started to creep in is the excitement of having an off-season and the Fifa windows being a break and being able to spend more time with my family and go on vacation and things like that that I haven't been able to do since I went to college. My niece's are getting older and I want to be able to spend time with them.

"And honestly, you can't play forever. And this seems like a good time to be done," she added, with a laugh.

SINCLAIR JERSEYS

Sinclair is one of Canada's most recognisable athletes. Crowds at matches are typically dotted with dozens of No 12 Sinclair jerseys, a number she chose as a young fan of Toronto Blue Jays' baseball Hall of Famer Roberto Alomar.

She was non-committal about her future after the World Cup but had fans abuzz late Thursday evening when she posted a cryptic Instagram video of white soccer boots hanging from a crossbar with the sounds of children playing.

Sinclair - known by teammates as "Sincy" or "Sinc" - is on the roster for Canada's friendlies versus Brazil on October 28 in Montreal and three days later in Halifax. Canada Soccer is expected to announce a pair of send-off games on Canada's west coast during the November 27 to December 5 international break.

There are bound to be tears.

"I'm sure," she said. "I definitely go through moments and right now I'm weirdly like really okay. But around games I'm sure I'll get emotional."

Sinclair has also led the Portland Thorns to three NWSL titles. They secured a bye to the semifinals where they will host a yet to be determined opponent on November 6.

Off the pitch, Sinclair was inducted into Canada's Walk of Fame in 2013 and made an Officer of the Order of Canada in 2017.

She is also active in raising awareness and funds for multiple sclerosis. Her mother Sandra died of MS in 2022, which Sinclair opened up about in her book "Playing the Long Game."
