Before it was known as Air Canada, Canada’s major airline was called TCA or Trans-Canada Air Lines. The leading railway companies in Canada — particularly Canadian Pacific and Canadian National — played an early major role in connecting the far-flung dots within that country’s vast borders. In 1937, one of those rail companies, Canadian National, in an effort to diversify, formed TCA thereby filling another vital transportation niche to serve Canada’s expansive geography as well as beyond. In 1965, TCA changed its name to Air Canada. These stylish travel posters from before 1965 (when its name was changed to Air Canada) harken back to TCA’s first few decades as a national flag air carrier.
