...are very hard to find. The parks dept would like you to book the BIG parks, and won't issue permits for the small ones for weddings. So you can hold a small informal elopement for a handful of people, if you are discreet and happy to fade into the less well known areas of parks, or the Rosedale Ravine, or Cherry Beach, or the Spit, etc. You could even discreetly gather on a NON-busy day at the foot of this pretty bridge on Center Island - which looks just like Bow Bridge in Central Park. Indoors, you can rent Allan Gardens conservatory for a small wedding (they say up to 40? seems crowded) and it's reasonable and very lovely.
But if you're dreaming of a bigger bunch of people in a sylvan glade, you may have to go out of town, to the Toronto Islands, or the Kortwright - though I disapprove of chairs in a forest [amended: we had a lovely simple wedding at the Kortwright where simple wooden chairs were on the path].
You could bring a folding chair for granny, but the rest of you should simply stand around and leave no footprint... The Toronto Regional Conservation Authority books most of the pretty places, including Black Creek Village (which also offers a glade and a green). The largest 'downtown' gathering option seems to be Woodbine "Millenium" Park, which holds 100 people, or so says the Parks Department. Kew Gardens gazebo is up to 50 people - all standing, of course, and the St. James Park (gazebo) downtown is 40 people. You can book the fountain at Center Island for 100 people, but need to ask the island authority first. Otherwise, the Music Garden has lowered its capacity from 40 to 20 people,.
Part of the problem with park weddings is the number of people who have gone before you and ruined it all - bridezillas with chairs and high heels and videocams and altars and arches and rice... So naturally, the caretakers of our common spaces try to minimize the damage, and have restricted weddings to easily monitored spaces.
How about a friend with a great backyard?
Or go camping!
The Brickworks is nice, tho you MUST get a permit.
Ask me about Todmorden Mills - outside of mosquito season.
Sometimes there's permits for Riverdale Farm.
I like RIVERDALE PARK, - also ask me (small groups, tho).
Also the green roof at the Big Carrot.
