Letter carriers angry about cuts to home delivery marked the first anniversary of the announcement with a protest.
Several dozen carriers gathered Thursday morning outside 300 Cremazie Blvd. East to show their displeasure.
The Canada Post employees say stopping home delivery will lead to job cuts and cause hardships for many Canadians.
They say people picking up mail at community mailboxes, especially in isolated areas, could be an easy target for thieves and vandals.
Residents of Charlemange, Repentigny, Bois-des-Filion, Rosemere and Lorraine lost door-to-door delivery in October, and all homes in Canada are scheduled to lose mail delivery in the next five years.
