A north-south Cavendish Blvd. link is the missing piece in the island of Montreal road network. Initial discussions on connecting its two parts started in the mid 1960s and major studies were done in 1981, 1988, 1992, 1995, 1996 and 2000.

The goal of the Cavendish extension project is to complete the road network to:

  • Create north-south link from Côte Saint-Luc to Borough of Saint-Laurent
  • Create east-west link to Décarie Blvd.

The Cavendish link will improve accessibility to, from and within this sector for all means of transport and to ensure that the traffic conditions are conducive to the economic prosperity and well-being of residents.

In the early 1960s, the Cavendish extension generally referred to the road’s push north from Fleet Rd., past the railway tracks and towards what were then empty fields. The first step was to extend it north to the St. Luc Rail Yards, which is what indeed happened. The second step, was to go even farther north, over the rail yards and towards Ville Saint-Laurent, Hwy 520, Hwy 40, and Hwy 13 in time for the 1967 World’s Fair.

The project stalled and eventually opposition from previous administrations of Côte Saint-Luc kept the project off the radar. However, since 1998, the city has supported re-launching the project. City officials have the governments of Montreal, Quebec and Canada, presented numerous briefs, passed resolutions and kept the issue front and centre.


Côte Saint-Luc has active support from Mayor Denis Coderre in Montreal including the project being listed in the three-year capital expenditures budget and reserves being placed on plots of land needed for the eventual extension as well as $222,000 being presently spent by the agglomeration of Montreal for the studies on the overpass/underpass route. Also, Quebec Finance Minister Carlos Leitao announced on June 6 that the province has officially ceded the Blue Bonnets land to Montreal. This is important news because it means that the Cavendish extension is absolutely necessary if the Blue Bonnets land is to be developed and is a required condition by Quebec.

Côte Saint-Luc also have local MNA David Birnbaum and MP Anthony Housefather working behind the scenes in Quebec City and Ottawa to secure the necessary funding, mayors from neighbouring communities all in support, and buy-in from Canadian Pacific, and Canadian National who own the land through which the road extension must pass.
