Purolator Inc.

Purolator Inc. is a Canadian courier that is 91% owned by Canada Post Corporation, 7% owned by Barry Lapointe Holdings Ltd. and 2% by others.

The company was originally organized as Trans Canada Couriers, Ltd. In 1967, it was acquired by the US manufacturer of oil and air filters Purolator of Fayetteville, North Carolina (founded as Motor Improvements Incorporated in 1923)—the name was originally an abbreviated form of "pure oil later". In 1987, the company returned to Canadian ownership. Although it retained the Purolator name, it has since had no connection with the oil filter business.

Purolator has partnered with UPS for deliveries outside of Canada.

Cargojet Airways operates Boeing 727, Boeing 757 and Boeing 767 aircraft for Purolator.

Since 2003, Purolator has organized an annual food drive in association with the Canadian Football League. Every season, fans in each city are invited to bring non-perishable food items to a selected home game, and Purolator collects and donates the food to local food banks. Also, for every quarterback sack in the CFL, Purolator donates the quarterback's weight in food to the food bank in the city where the game was held.

On April 28, 2008, Teamsters Canada, the official union of Purolator truck drivers, package handlers, couriers, and other workers, gave employees a 72-hour strike warning. A tentative agreement from one month prior was rejected by 51% of Purolator union members. Purolator and its union met with a federally appointed mediator and reached a 2nd tentative agreement on April 30, around 24 hours before the strike deadline.
