Saint Laurent Boulevard's cardinal direction, on a pseudo north-south axis strongly deported to the west, and aligned with the summer solstice's setting sun, was outlined by the Sulpicians towards the end of the XVII century. The first post-colonial landowners of the island, then preoccupied to develop a genuine urban cadastre on the Coteau Saint-Louis, built a small street, which they named Saint-Lambert, perpendicularly to Notre-Dame Street. Saint-Lambert Street is clearly identified on a plan drawn by François Dollier de Casson in 1672. In the early XVIII century, when the lords of Montreal decided to develop agricultural land further north on the island, they prolonged this little street to build a "King's Way" exactly along the same axis and named it Chemin Saint-Laurent.
