Canadian Meteorological Centre
The Canadian Meteorological Centre (CMC; French: Centre météorologique canadien), located in Dorval, Quebec, is the branch of Environment Canada's Meteorological Service of Canada that is tasked with providing forecast guidance to national and regional prediction centres, and is responsible for running the Global Environmental Multiscale (GEM) model, often referred to as the CMC model, together with its regional and ensemble variants. It is made up of three branches: 
The Informatics Branch provides centralized computing and telecommunications services to meet the Atmospheric Environment Programs' objectives, support other departmental operations, and assist other approved users. It operates and maintains the supercomputer facility in Dorval and various telecommunications networks. The Operations Branch is responsible for the meteorological operations of numerous production systems for weather, climate, air quality, and environmental programs at the Canadian Meteorological Centre. In addition, the Branch provides highly specialized support to environmental emergencies.
