5 Canadian Mechanized Brigade Group

5 Canadian Mechanized Brigade Group (5e Groupe-brigade mécanisé du Canada) (5 CMBG) is a Canadian Forces brigade group that is part of 2nd Canadian Division of the Canadian Army. It is based at CFB Valcartier, near Quebec City, Quebec. The brigade group is the formation responsible for the majority of francophone units of the regular army.

Units
Three regular force units of other formations (430 Tactical Helicopter Squadron and 5 Field Ambulance of Canadian Forces Medical Group) are collocated with 5 CMBG at CFB Valcartier and work closely with the brigade group, but are not officially a part of it.

History
During the 1970s and 1980s, the 5th was the primary formation of the Canadian Air-Sea Transportable Brigade Group (CAST), supported by additional artillery and light armour units, as well as two wings of Canadair CF-5 aircraft. The CAST mission was disbanded in 1989.
