Throughout the 1960s and 1970s Toronto's planners and policy makers were little seduced by the city's old buildings, and in many cases sought to expand and develop Toronto from the ground up.

There are countless ways that one could track this particular strand of Toronto's story — by looking at plans for superhighways, at the grand buildings lost to demolition, or even at aerial photos that depict the changing shape of the city — but the starkest visual evidence is the preponderance of parking lots in the downtown core during this period.

At the time, buildings weren't just knocked down in order to be replaced with newer structures, but to sit in limbo before development eventually proceeded.

Perhaps the best example of this involves the former Board of Trade Building, located at Yonge and Front streets, which was knocked down in 1958 only to sit vacant (save for a few parked cars) until construction began on the EDS Building in the early 1980s.

Most of the empty spaces in these images have since been filled via Toronto's various real estate and development booms, though some not until more recently than you might think.

It nevertheless remains mind-boggling to see just how thinned out these areas were only 30 years ago, particularly considering that they were generally quite dense to begin with. Here's a look at Toronto of the 1960s and 70s, a place where it was never hard to find a parking spot.

Behold, that time when Toronto was a city of parking lots.
