Montreal Light, Heat and Power

The Montreal Light, Heat and Power Company (MLH&P) was a utility company operating the electric and gas distribution monopoly in the area of Montreal, Quebec, Canada, until its nationalization by the government of Quebec in 1944, under a law creating the Quebec Hydroelectric Commission, also known as Hydro-Québec.

Hydro-Québec ran both of MLH&P's electric and gas operations until 1957, when its gas properties were sold to the Corporation de gaz naturel du Québec, known today as Gaz Métro.

The company was established in 1901 as a result of the merger of Rodolphe Forget's Royal Electric Company and Herbert Samuel Holt's Montreal Gas Company.
