Since the early 20th century, Montreal Road has been the cultural core of Vanier.
[1][2] It is one of a string of variously named roads that form an uninterrupted route between Parliament Hill and the City of Montreal, originally part of Ontario Highway 17, later bypassed by the freeway now known as Ottawa Road 174.
The insertion of de in the 2010s marked a departure from the City's general bilingual street-naming policy to align with Francophone practice for streets that refer to place names.
East of St. Laurent Boulevard, it becomes a four-lane arterial road that divides several neighbourhoods such as Beacon Hill.
Future plans by the city could include an LRT corridor on this stretch as far as Blair Road, where the City has plans for a new "main street" development of shops and apartment towers.
