You're thinking of the Ertefa meets, most likely, which pretty much got shut down for good a few years ago. I think Ertefa may now hold 1 or 2 events per year and I think that these 1 or 2 meets are held at other locations.

The Kennedy Commons meets have now also been shut down.

Seems like most places have no interest in holding car meets anymore these days.

theres only 3 main ones in and around the GTA that are still worth going. theres Car mania in pickering. the Ertefa meets whenever they pop up. last year there was only one at markham fairgrounds and the Strada meets.
