Inexpensive locations for smallish weddings

Are hard to find, yes?  For a simple wedding ceremony, everybody standing,  here are some ideas.  Do try small restaurants.  Almost ANY restaurant will be happy to accommodate a group for dinner or cocktails or brunch, but don't say 'wedding' until you chat about the room and food. Then say "small private event, with a short little ceremony".  Do check hotel rooms! You can probably find a suite in most hotels, suitable for a meeting for a dozen or so - often with a view! Ask friends and relatives about  Condo party rooms, or nice lounges they have seen, including, rooftops, back patios, all very suitable for a nice wedding.  Or try:

Co-working spaces - CSI, etc.  Book a meeting room.
AirBnB apartments with balconies

Your friend's condo party room.
Restaurants with decks, patios, if you eat there after.
Good old Trinity Bellwoods (but you may have to share the space with the denizens of the park - animal and human - same thing with Dufferin Park or Christie Pitts)
Pick a piece of waterfront that isn't owned already - Sunnyside or the Beaches
The Music Garden, Harbourfront (no chairs, 20 people). No shelter for rain.
 Hart House Chapel. 30 people max. Also other small pretty rooms available.
Allan Gardens   12-40 people? No chairs. Lovely plants, and rainproof.
The Multifaith Centre at University of Toronto - lots of nice rooms for 6-100 people ask Mary (Chaplain at UofT) especially if you are staff or student.
Cafe on the Toronto Island - including their terrace.
Small terrace area and private room at Le Select Bistro -they're back, check re weddings.

Grange Park, Riverdale Park, Withrow park - or your local parkette.
