The Canadian Golden Age of Comics, as it is now known, came about thanks to government intervention. In December 1940, the feds, responding to a trade deficit with the U.S., introduced the War Exchange Conservation Act, restricting imports of non-essential goods, including fiction magazines and comics, which had become ubiquitous after the 1938 introduction of Superman, drawn by Toronto-born Joe Shuster, and Batman the following year.
hello Canada Jack, Commander Steel, Johnny Canuck and Nelvana of the Northern Lights! These characters thrived for a few years, but after the war ended, the borders reopened to the likes of DC and Timely, as Marvel was then known. This and the waning popularity of superheroes led to our national defenders hanging up their costumes, largely to be relegated to the dustbin of history.
