Among the favourites to lift the trophy, the Canadians have been rocked by an ongoing labour dispute between governing body Canada Soccer and the country's national teams. 

The Canadian women's team recently escalated their protest over pay-equity issues when they wore purple shirts reading 'Enough is enough' ahead of their match against the USA in the SheBelievesCup. 

"While I have been one of the biggest proponents of equalising the competitive performance environment for our Women's National Team, I will unfortunately not be leading this organisation when it happens," Bontis, who had been president since November 2020, said in a statement.

"I acknowledge that this moment requires change."

The women's national team's last agreement with Canada Soccer expired in 2021 while the men - who formed their own players' association last August - are negotiating their first formal deal. 

Both programs say their budget is being cut.
