The 1964 Automotive Products Trade Agreement or "Auto Pact" represents the single most important factor in making the Canadian automotive industry what it is today.

Before the Auto Pact the North American automobile industry was highly segregated.

The most significant of these agreements was the 1960s Automotive Products Trade Agreement (also known as the Auto Pact).

They also raised concerns about how Canada's social programs and other trade agreements such as the Auto Pact would be affected.

Key features of the Auto Pact were the 1:1 production to sales ratio and Canadian Value Added requirements.

A good example of this is the automobile industry, which can be clearly demarcated into two periods: before and after the free trade creating Auto Pact of 1969.

After the Auto Pact, the industry was transformed as a unified North American market was created.

Aided by the Auto Pact and the weakening Canadian dollar in relation to the United States dollar, a geographic difference developed which provided some relief to many Canadian auto-workers.

The signing of the Auto Pact with the US in 1965 created massive investment in auto production facilities in Toronto and southern Ontario.

It treats American and Canadian content the same, under terms of the Auto Pact that integrated the nations' automotive industries in 1965.
