Two Mexican media outlets are reporting the Canadians were on board a sailboat that ran into strong winds earlier this week on Lake Chapala near Guadalajara.
The Guadalajara publication Informador reports on its website that authorities have found the bodies of two Canadians, while a third remains unaccounted for.
Foreign Affairs says it's in contact with local authorities and is providing consular assistance to the families.
The department isn't releasing the identities of the Canadians.
