Canwest Global Communications Corporation, which operated under the corporate brand Canwest, was a major Canadian media company based in Winnipeg, Manitoba, with its head offices at Canwest Place. It held radio, television broadcasting and publishing assets in several countries, primarily in Canada.

Canwest entered bankruptcy protection in late 2009, leading to the sale of the company's assets. Canwest's newspaper arm was sold to a group of creditors led by National Post CEO Paul Godfrey, through a newly formed company named Postmedia Network. The sale of the company's broadcasting arm to Shaw Communications closed on October 27, 2010, after CRTC approval for the sale was announced on October 22; those assets are now collectively known as Shaw Media.

Following the sale of assets, the company was renamed 2737469 Canada Inc., ceased to carry on business, and commenced bankruptcy proceedings under the Bankruptcy and Insolvency Act. The company is still registered as an "active" corporation with Industry Canada as of June 2011, but this merely indicates that the aforementioned bankruptcy proceedings continue.
