The national team players are upset and concerned about budget cuts on the women's side and will not participate in any team activities.
"We have been told, literally, that the Canadian Soccer Federation cannot adequately fund the women's national team and they have waited to tell us this now - when we are six months from the World Cup," the team wrote in a statement.
Choose not to participate
Canada won Olympic gold in Tokyo 2021 after defeating Sweden in the final and qualified last summer for the World Cup in Australia and New Zealand.
The national team is scheduled to play in the SheBelieves Cup tournament in February, against the United States, Brazil and Japan, but team captain Christine Sinclair and teammate Janine Beckie have told TSN they have no intention of participating in any Canadian Soccer Association activities until the matter is resolved.
"It's gotten to a point, at least for me, where I can't represent the union until this is resolved," Sinclair said.
"Deeply disappointed"
Canada's men's national team supports the women's national team.
"The Canadian men's national team is, once again, deeply disappointed by the federation's actions and supports the women's national team," they write.
The Canadian players - both women and men - are in talks with the union about a new collective agreement where the women seek equal pay to the men.
The WC in Australia and New Zealand will be played between 20 July and 20 August.
In the group stage, Canada faces Australia, Ireland and Nigeria.
