They were first built in 1974 for the then Toronto Metro Roads and Works department to remove major snow accumulations from roads managed by Metro Toronto.
Built by Trecan Combustion Limited[1] of Hubley, Nova Scotia, the city operates a fleet of 5 machines (8 wheeled self driven (with driver cab) vehicles are stored at Toronto Works Ellesmere Yard in Scarborough) along with the 350-PD unpowered snowmelter trailer units by Trecan.
Trecan Metromelt and snowmelters are used throughout Canada, the United States and Russia.
[citation needed] Mobile self-propelled snowmelters were originally invented and patented in Canada,[2][3] European Union[4] and the US[5] by Albert Z Morin, the original inventor of the Jet Melt and likewise renowned and honored by Canada's highest innovation award for inventing the aerodynamic mudflap.
The machine is self-propelled and self-loading, and resembles a large truck-mounted furnace with a snow-gathering conveyor belt at the front end.
