It was a creosote wood treatment plant from 1924 to 1964. There's a lot of information about it online if you search for "Canada Creosote Calgary". There used to be a really good and detailed document about the plant and the contamination issues, but it appears to be gone now.
My understanding is that when the plant closed, cleanup of the site was minimal. In the late-80s, a study was conducted that determined the contamination had spread across the river into West Hillhurst. Containment measures were implemented in the mid-90s and it is continually monitored.
The car dealerships and Greyhound depot have likely contributed their own contamination in the decades since the Creosote plant closed.
