Who Founded Montreal? A Clear Look at the Founders of the City

Who Founded Montreal? A Clear Look at the Founders of the City

Montreal was founded on May 17, 1642, when a small French missionary group established Ville-Marie, the settlement that would later grow into today’s Montreal. Although Paul de Chomedey, sieur de Maisonneuve is traditionally credited as the city’s founder, modern research and official recognition now confirm that Jeanne Mance played an equally essential role as a co-founder.

Together, they shaped the early colony—one through military and civic leadership, the other through medical care, administration, and strategic financial support.

Who Is Considered the Founder of Montreal Today?

Modern consensus recognizes:

  • Paul de Chomedey de Maisonneuve as the founding leader and military commander, and

Both are now understood as joint founders, each contributing indispensable leadership.
