Canada's women's football team has gone on strike to protest inequality and lack of funding less than six months before the World Cup.

"We are tired - tired of constantly having to fight for fair and equal treatment," said a statement issued by the women's squad.

"Enough is enough," tweeted captain Christine Sinclair.

The men's team on Sunday released a statement saying they "wholeheartedly supported" the women.

Concerned about "significant cuts" in the 2023 budget, the women, who are in Orlando, Florida, ahead of the She Believes Cup, have decided not to train or play any matches.

"With the biggest tournament in women's football history less than six months away, our preparation for the World Cup and the future success of the Women's National Team program are being compromised by Canada Soccer's continued ability to support its national teams."

Canada Soccer responded on social media that "pay equity for our women's national team is at the core of....negotiations. Canada Soccer will not agree any deal without it."

Canada Soccer said they hoped to meet with the players on Sunday.

The players have been negotiating for more than a year with the federation, but say they are still in "limbo".

"The way Canada Soccer allocates or uses funds is unclear and full of secrets," the players wrote in a statement.

In 2019, the American women's team filed a complaint against their federation for discrimination in a court in Los Angeles. The US Soccer Federation offered pay parity with the men's team in 2021.

The Women's World Cup will be held in Australia and New Zealand, from July 20 to August 20.

Canada's women's team are eighth in the FIFA rankings and in 2021, they won gold at the Tokyo Olympics.
