Produced from 1947 to 1968, the Mercury M series was sold primarily in Canada, as a rebadged version of the Ford F-Series.

Alongside the creation of the Monarch and Meteor sub-brands, Ford of Canada introduced trucks to the Mercury division.

At the time, few rural communities offered both the Ford and Lincoln-Mercury dealership networks, miniminizing model overlap and allowing for greater coverage for potential truck buyers.

From 1948 to 1950, nominal tonnage ratings were replaced by a series designation in which the numbers indicate the GVWR when equipped with tires of appropriate capacity.

While not sold as a Mercury, the Lincoln-Mercury division also marketed the first-generation (1957-1959) Ford Ranchero through its Meteor brand in Canada.
