Canadian Women's Open - Name Changes

Name Changes

The tournament was first known as La Canadienne; it later became the Peter Jackson Classic (after a brand of Imperial Tobacco cigarettes); it was also called the du Maurier Classic (a reference to du Maurier cigarettes) until Canadian tobacco restrictions came into force.

From 1988 to 2000 both Classique du Maurier Ltée and du Maurier Ltd Classic were official because of Canada's Official Languages Act. In 1988, the tournament added the Ltd/Ltée designation because of the Tobacco Products Control Act. Under the rule, the full name of the manufacturer was required on promotional material as opposed to a tobacco brand name, so Imperial Tobacco registered their brands as separate corporate entities to avoid the ban.

In 2001, the Bank of Montréal took over sponsorship of the event for five years and renamed it the BMO Canadian Women's Open. In 2006, the Canadian National Railway Company (CN) became the new title sponsor of the event, now called the CN Canadian Women's Open.
