Two spots I know of that are super active at night:
1) High Park (somewhere near the zoo)
2) Marie Curtis Park
Where do you go?
Ross Lord Park, at least before the pandemic (I haven't been there since). Off the second parking lot, walk past the restrooms and into the woods behind the open field. That area's crawling with horny perverts ... and dogging women know it. Best time to go is mid summer night right around dusk. Go in there in a miniskirt and no panties, and you will get the biscuit buttered 20 times in 10 minutes.
