The children have Canadian maple leaf cards. Can parents work legally?

It can't be legal The Canadian Maple Leaf Card is an identification document for permanent immigrants in Canada, which is similar in nature to the American green card, rather than the immigration paper used in Canada in the early days. According to the relevant laws of Canada, only people with Canadian citizenship or permanent resident status can work legally, and the fact that their children have Canadian maple leaf cards does not mean that their parents have maple leaf cards. Therefore, if parents do not have Canadian citizenship or permanent resident status, they cannot legally work in Canada.
