Ontario: cities, venues and capacity
Where to put an event in Ontario. 63 cities, 880 venues, and the practical differences between them.
Rogers Centre states the largest capacity in the province. The dots show what event67 would bill at that head count, and where the price stops.
Ontario in figures
Ontario is a province of Canada of about 14 million people. Toronto is the capital.
The mapped inventory comes to 43 exhibition or convention halls, 73 dedicated conference and function spaces, 222 arenas and stadiums, 163 theatres and concert halls and 379 independent event spaces.
Ontario spans 2 time zones — Toronto time and Winnipeg time. Publish one zone in the app and say which it is, or half the room arrives an hour out.
The largest stated capacity anywhere in the province is 39,150, which is the practical ceiling for a single-room programme here.

The largest venues in Ontario
Ranked by stated capacity, then by how much the record can prove. Open data rarely publishes a capacity for a convention centre, so a hall may sit below an arena here without being the smaller room.

|---|---|---|---|
| Rogers Centre | Toronto | stadium | 39,150 |
| Mississauga Celebration Square Amphitheatre | Mississauga | concert hall | 30,000 |
| TD Place Stadium | Ottawa | stadium | 24,000 |
| Hamilton Stadium | Hamilton | stadium | 22,500 |
| Varsity Stadium | Toronto | stadium | 21,767 |
| BMO Field | Toronto | stadium | 21,566 |
| Scotiabank Arena | Toronto | arena | 19,800 |
| Canadian Tire Centre | Kanata | arena | 19,153 |
| TD Coliseum | Hamilton | arena | 19,000 |
| York Lions Stadium | Toronto | stadium | 12,500 |
| Maple Leaf Gardens | Toronto | arena | 12,473 |
| TD Place Arena | Ottawa | arena | 9,862 |
Ontario city by city
63 in the dataset, largest first. Each guide covers that city's venues, its airport, its local time and a worked price for an event of that size.
One more town has a venue worth its own guide
The town itself is too thinly mapped for a city guide, but the venue publishes enough to stand on its own.
- Little Current: Debajehmujig Creation Centre
Also in Ontario, with nothing mapped yet to build a guide from: Ottawa South, Thornhill and Willowdale. They appear here rather than as pages with three facts on them.

Questions people actually ask
Which Ontario city is best for a conference?
It depends on how many people you need to seat and how they arrive. Toronto has the deepest venue list in this province. The table above ranks every covered city by how many venues are mapped in it, which is the closest proxy to choice you will get before you start calling.
How many event venues are there in Ontario?
880 venues across 63 cities are mapped in this dataset, of which 44 are convention, exhibition or conference facilities. That is what open data records, not a complete registry — small function rooms inside hotels and community buildings are consistently under-mapped everywhere.
What does event67 cost for a Ontario event?
950 activated attendees means 900 billable after the free 50, so CA$6,300 for the event. The rate is CA$7 per activated attendee beyond the first 50, and the total for one event stops at CA$6,650 however many more attend. Activated means the person claimed their invite and opened the app. Not when you import them, not when the invite is delivered, and not if they register and stay home.
What is the biggest venue in Ontario?
Rogers Centre, at a stated 39,150. That is the practical ceiling for a single-room programme anywhere in the province; above it you are splitting the audience across buildings or looking outside Ontario.
Does Ontario span more than one time zone?
Yes — 2: America/Toronto and America/Winnipeg. Publish the schedule in the venue's zone, name the zone in the app, and every attendee's phone converts it correctly from there.
