Canada Post Corporation is the federally mandated postal authority, responsible for letter and parcel delivery to all Canadian addresses including rural and remote ones. Rural Route carriers are typically contracted operators who use their own vehicles to cover designated routes, often spanning 80–160 kilometres per day.
The Canadian Transportation Agency and provincial ministries of transportation set standards for road maintenance that directly affect carrier ability to complete routes. When a provincial road becomes impassable, Canada Post protocols determine whether service is suspended or rerouted.
First Nations communities on reserve lands present distinct delivery conditions. Many reserves are served by a single post office rather than door-to-door delivery, and the distances between the nearest Canada Post facility and individual homes can exceed what urban standards would consider the "last mile" by an order of magnitude.
