The Postpar letter service was introduced in September 1987, a year in which labour disputes between postal workers and the Government resulted in two major disruptions of mail service. In June and July, members of the Letter Carriers' Union staged a 19-day strike. In the fall. the Canadian Union of Postal Workers organized rotating strikes from region to region, but the Montreal workers staged a general walkout.
Postpar serviced the business community delivering letters to other businesses and to residential addresses. offering a letter service within the area encompassed by the following postal codes:
- all of "H"
- J3Y and J3Z
- all of J4
Postpar letter rates were cheaper than those charged by Canada Post.

Thousands of Postpar letters delivered to the wrong addresses were dropped in Canada Post mail boxes for return by persons believing that the letters had been delivered by Canada Post. Canada Post was required by regulation to return these letters. By April, 1988, Canada Post had to handle 27,000 pieces of returned Postpar letters without postage, an effort which required the full-time service of two persons.
Canada Post advised Postpar that it should provide guaranteed return delivery, in response to which Postpar prepared markings providing telephone numbers to be called if the addressee had moved.

On September 8, 1988, Canada Post succeeded in obtaining a permanent injunction against the operations of Postpar Inc. from violating the exclusive privilege conferred upon Canada Post Corporation of collecting, transmitting, and delivering letters within Canada.
Postpar Inc. complied with the injunction, but in its brief history is believed to have delivered millions of letters in the Montreal area.
