History
In 1931, as the end approached for Durant Motors, the Canadian Durant factory at Leaside became an independent company. Dominion Motors Limited received its charter on March 14, 1931, and on May 4, 1931 Durant Motors of Canada was dissolved, with all its assets taken over by Dominion Motors.
The Durant name was quickly dropped from the cars in favor of Frontenac. The first Frontenacs were based on Durant designs; later models were based on De Vaux designs, some of which appeared as Continental cars in 1933 after De Vaux went out of business.
Dominion Motors ceased production in December 1933.
Models
Model E (6-18)
The first car built by Dominion Motors under the Frontenac name. Based on the Durant 6-19, with changes to wheelbase, engine size and body detail. De Luxe models had “free wheeling” and the Startix automatic starting system as standard. Fact sheet: 1931 Frontenac E.
6-70 (Frontenac Six)
Introduced in 1932 to replace the Model E; essentially an E with trim updates. Fact sheet: 1932 Frontenac 6-70.
6-85
Introduced in the spring of 1932 and based on the 1932 De Vaux 6-80, with a “simplified” free wheeling and automatic starting. Fact sheet: 1932 Frontenac 6-85.
ACE
A special-order 1933 Continental Ace, imported from Continental’s Grand Rapids factory rather than built at Leaside. Fact sheet: 1933 Frontenac ACE.
C-400
The four-cylinder 1933 C-400 was based on the Continental Beacon. It sold for half the price of the previous year’s Frontenacs, a sign of the economic conditions of 1933. Fact sheet: 1933 Frontenac C-400.
C-600
The six-cylinder 1933 C-600 was based on the Continental Flyer. Fact sheet: 1933 Frontenac C-600.
