HISTORY OF THE SITE
Amherst and Square Amherst Streets were named after Jefferey Amherst, the first governor of New France from 1760 to 1763. It’s of note that he died in Sevenoaks in England in 1797 in his residence, which was named Montreal.
Square Amherst Street was so named because of the presence of a square of the same name in front of the Saint-Jacques Market. This planning appears on a 1915 map.
