I had Rusty Snaketails at Erindale Park, Mississauga last year. I'm not totally sure whether I'll be around in June, but contact me if you want to go look for them! I've also had Unicorn Clubtail, Eastern Amberwing, "Red" Saddlebags, Rainbow, Taiga and Stream Bluet here among other stuff.
I've just had one green darner so far, but it really won't be long until the first forktails are out.
