Local resident Shawn Bergman said the bird had adopted the neighbourhood as his home. He told The Canadian Press: "He just built a nest this year and that’s basically what got him all up in arms."

Some residences have gone months without mail deliveries as a result.

Canada Post spokesman Phil Legault said in a statement to AFP that the safety of its employees is "of most importance."

He cited several incidents "in this neighborhood when our letter carriers were attacked by a crow."

Residents, he said, have been advised where to go to pick up their mail, adding that postal service would resume "as soon as possible when it's safe."

A bird believed to be the very same crow gained notoriety in 2016 for stealing a knife from a crime scene.

It has also been spotted riding the city's metro and earlier this month got into a flap with a McDonald's diner while trying to steal her breakfast.
