Questions have yet to be answered in the dispute over prize money, as the Canada men's national team resume training.
Canada Soccer was accused of disrespect by the players who went on strike on Sunday.
In a letter released on Monday, they said they met with leaders of the country's football association but "we have not reached an agreement".
Both parties will keep negotiating.
In a statement posted shortly after on social media, Canada Soccer said there were "future meetings scheduled toward a resolution".
The friendly with Panama was canceled due to the players' strike.
Canada will play in the men's finals of the World Cup for the second time in their history, having played in 1986.
There were conflicting reports about the amount of prize money offered to the players.
TSN first reported that national team players had been offered about 10% of the total amount the country would get from Fifa, set to be at least $10 million (£8m).
The players on the men's and women's teams asked for 100 percent of the 60 percent split offered by Canada Soccer.
The men's team is going to play in a Nations League match in Canada.
