To the best of my knowledge, the track opened in 1956 and closed in 1970. Prior to construction of the car racing track, this same location had a horse-racing track.
The 1960's saw a decline in activity here, tapering continuously until its closure the following year.
I stumbled upon mention of this online as I was looking for information on other locations in Wasaga Beach. I made a mental note of it and decided to go there on our next visit. As it turns out, I didn't have to wait too long. We took a slow walk around the turns and found it difficult to imagine, by today's race-track standards, how anyone could safely run a race here.
