Inexpensive Wedding Venue... Toronto Area

Help me, if you can!

My fiance and I have been engaged for over a year and a half now, we've been trying to find the perfect venue for our upcoming (hopefully) reception.. However, its been extremely difficult to find something within our budget, thats also what we want.
If we had our way, we'd have a BBQ on the Island or in a park, with 60-80 of our friends and family, for under $3000, BUT, since we all know that wont happen, I'd be happy to find somewhere else to do this.

I need suggestions, I'm lost. I'm getting upset, partly because without a car (TTC only), its difficult to check places out.

I guess what I'm looking for is:

- An entire reception for as little as possible, including food/venue
- A picnic/BBQ feel vibe (i hate banquet halls)
- Shelter if it rains
- Wicked service

I'd love you forever if you could help me out.

Thanks so much,
