Its southern end is at the junction of A-20 on the Island of Montreal near Pierre Elliott Trudeau International Airport.

However A-13 was not built beyond its interim terminus at A-640, leaving only A-15 to connect Mirabel with Montréal island.

Boulevard Pitfield is routed as a parallel service road to A-13 in St-Laurent.

In the 1920s, the actual route was a Polo Pony Trail leading from the various estates of the Saraguay Village residents to their Polo Fields, now where the area of St. Laurent Blvd and Bois Franc merge.

Over the next several decades Saraguay Farms, owned by Mrs. W.C. Pitfield, was paid to clear the road in the winter by the municipality of St. Laurent.
