Toronto's most immersive cinema — the IMAX dome at the Ontario Science Centre projects films onto a 24-metre curved screen that fills peripheral vision completely. Nature documentaries, space films, and special programming make it extraordinary for children and adults equally. Often overlooked in favour of the science centre itself.
Neighbourhood: Don Mills / East York · Address: 770 Don Mills Rd, Toronto, ON · Hours: Mon–Fri 10am–4pm | Sat–Sun 10am–5pm | IMAX screenings throughout the day
Why Visit
The Ontario Science Centre IMAX isn’t your typical movie theatre—it’s a giant dome where documentaries and science films fully surround you. It’s an everyday Toronto secret that’s thrilling for first-timers and repeat visitors alike.
What Makes It Unique
Unlike flat-screen IMAX theatres downtown, this dome envelops your vision with a 180-degree curved screen over 24 metres wide. The film selection skews educational, leaning hard on nature and space content you simply can’t see elsewhere in this format. It’s a rare holdout of ‘classic’ IMAX you won’t find at the multiplex.
If you’ve never seen a film in a real dome IMAX, the Ontario Science Centre’s theatre can feel a little ridiculous at first—in the best way. You walk in expecting a movie screen, and instead you get this enormous curved wall of image rising above you, wrapping so far into your peripheral vision that after a minute your brain stops treating it like “watching a movie” and starts reacting like you’re inside it. For space films especially, it’s kind of wild. When the camera drifts over Earth or plunges through star fields, you actually feel that little stomach-drop you usually only get on rides.
It’s at 770 Don Mills Road, in Don Mills / East York, and a lot of visitors focus so much on the Science Centre itself that they barely think about the IMAX. That’s a mistake. The theatre is one of the most memorable parts of the whole place, especially if you’re going with kids who are old enough to sit through a feature-length documentary without melting down. Even adults who think documentaries are “fine” tend to come out grinning. The format does a lot of the work. Nature films suddenly feel huge and physical—oceans, forests, Arctic landscapes, close-up animal footage all land differently when the image fills your field of view.
The atmosphere is fun without feeling fussy. You’ll see families with excited kids, grandparents, science nerds, and movie people who came specifically for the dome. It’s not a regular multiplex crowd, and that’s part of the charm. People are there because they actually want to see the film, not just kill time. Once the lights go down, there’s usually that quick moment of collective “whoa” when the full screen kicks in.
My honest advice: pair it with general Science Centre admission if you have the time. Do a few hours wandering the exhibits, grab a break, then sit down for an IMAX show when everyone’s legs need a reset. It turns the day into something much more complete, especially for families. If your kids are into planets, dinosaurs, oceans, weather, or animals, check the schedule ahead of time and pick the film first, then build the rest of the visit around it. The nature and space documentaries are the ones I’d prioritize every time.
A practical note: sit somewhere near the middle rather than too close unless you really want the full neck-craning effect. In a dome theatre, “closer” isn’t always better. Also, some younger kids love it instantly, while others find the scale intense for the first few minutes, so it helps to give them a heads-up that the screen is enormous and the sound can be big too.
If you like cinemas, this place is worth going out of your way for. And if you’ve only ever done standard theatres, the dome is a reminder that watching a film can still feel surprising. No normal screen comes close.
