The Canadian National Railway owns this 4.97 km tunnel straight through Mont Royal and the alkaline intrusion that formed it. Mont Royal is one of the Monteregian Hills that also includes Mont Saint-Hilaire.

Specimens recovered from the excavations were intensely studied at McGill in the 1922-30 period and some are on display at the Redpath Museum, McGill University campus.
The coordinates given are for the North portal of the tunnel, the south portal is under large buildings in downtown Montreal near Gare Central (Central Station of CNR).
