The Mallard is found across Canada, but is most numerous in the Prairie Provinces. Mallards have recently been spreading eastwards and are firmly established in New Brunswick along the St. John River.

Mallards have also spread north into boreal forest zones in eastern Canada and along the James Bay and Hudson Bay lowlands. The male Mallard in breeding dress is unmistakable.
