The network was first formed in early 2001 when Global bought CHCH-TV in Hamilton, Ontario, formerly known as OnTV. The station airs several hit U.S. programs, but often Global, which is a more national network, cherry-picks some of CH's hits and airs it on the main network.
The other three CH stations are the former CHEK in Victoria, British Columbia, CKRD in Red Deer, Alberta, and CJNT in Montreal, Quebec.
