Ontario Science Centre guide
Toronto: Ontario Science Centre Skip-the-Line Entry Ticket
Is the Ontario Science Centre still open?
The original Don Mills Road building closed, and the institution has been operating on an interim basis while a new permanent facility is developed at Ontario Place. Because the situation has continued to evolve, check the current operating status and address directly before planning a visit rather than relying on an older guide or search result.
A guide that needs to be read differently than most attraction pages
Most attraction guides can describe hours, layout, and pricing with confidence because the venue isn’t changing. The Ontario Science Centre is a genuine exception right now: its original Don Mills Road building, a Toronto landmark since 1969, was closed after structural issues were identified with the roof, and the institution has been working through interim arrangements while a new permanent facility is developed at Ontario Place on the waterfront. That’s a meaningful, ongoing transition rather than a settled situation, which means the most useful thing this guide can do is be explicit about what’s confirmed, what’s likely to keep changing, and how to verify current details before you build a day around a visit.
| Status | Original Don Mills building closed; interim programming running elsewhere |
| Cost | Roughly CAD $20s-30s for adults, less for kids — confirm at booking |
| Time needed | 2-3 hours, likely smaller-scale than the original building |
| Best for | School-age kids through early teens interested in hands-on science |
| Booking | Verify current address and hours directly before finalizing plans |
What happened to the original building
The Don Mills Road location, a landmark of Canadian modernist architecture designed by Raymond Moriyama, closed after an engineering assessment found structural problems with sections of the roof that made continued public occupancy unsafe. This wasn’t a gradual wind-down or a funding-driven closure — it was a sudden, safety-triggered shutdown, which is part of why interim arrangements have had to be worked out on relatively short notice rather than planned years in advance. The original building’s future — renovation, redevelopment, or another outcome — is a separate question from where the science centre’s programming operates in the meantime.
Where the science centre operates now
Interim programming has been run from alternate locations while the province develops a new, purpose-built permanent facility at Ontario Place, intended to anchor a broader redevelopment of that waterfront site. Because interim arrangements are, by definition, temporary and have already shifted since the original closure, this guide won’t pin down a specific current address — check the science centre’s own official channels directly before finalizing a visit, particularly if you’re planning a trip weeks or months ahead. This is the single most important piece of advice in this guide: verify before you go, rather than trusting any secondhand description, including this one, as current.
Ontario Science Centre skip-the-line entry ticketWhat’s likely unchanged: the format, if not the building
The core appeal of the Ontario Science Centre was never really about the Don Mills building itself — it was the hands-on, experiment-driven exhibit format that let kids interact directly with demonstrations rather than reading placards next to glass cases.
That philosophy has generally carried over into interim programming, though the physical scale, exhibit count, and specific installations at an interim location are very likely smaller than the original building’s decades of accumulated exhibits and dedicated spaces like the Shoppers Drug Mart Kidspark or the OMNIMAX dome theatre. Treat interim visits as a genuinely different, more limited experience than what older reviews or pre-closure guidebooks describe, rather than assuming a like-for-like replacement.
The new Ontario Place facility
The long-term plan centers on a new, purpose-built science centre as part of the broader Ontario Place redevelopment on Toronto’s waterfront. Public infrastructure projects of this scale routinely see their timelines shift, so this guide won’t state a specific opening date — check current provincial and Ontario Science Centre announcements for the latest projected timeline rather than relying on an estimate that may already be outdated by the time you read this.
How to plan around the uncertainty
If a science centre visit is a priority for your trip, build in flexibility: confirm the current location and opening hours no more than a week or two before arrival, have a backup plan in case hours or access change on short notice, and don’t structure an entire day’s itinerary around it without a fallback. Ripley’s Aquarium of Canada is the most comparable stable alternative for an indoor, hands-on-adjacent family experience if the science centre’s current hours or location don’t line up with your trip. The things to do in Toronto on a rainy day guide lists several other indoor options worth having on hand as a backup regardless.
Ticket pricing
Pricing for the current interim programming has generally tracked close to the venue’s historical range — adult tickets in the mid-20s to low-30s CAD, with reduced pricing for children and youth — but confirm current pricing at booking, since it can shift with a change in venue scale or exhibit count. Booking ahead is worth the small extra step here beyond the usual “avoid the line” reasoning: it also forces a check of the current address and hours before you show up.
Who this attraction still suits
Kids with a strong interest in hands-on experiments, physics demonstrations, and interactive exhibits over passive viewing are the best fit for the science centre’s format, interim location or otherwise. It tends to land less well with toddlers who need open physical space to move rather than structured exhibits — for that age group, the Toronto Islands or a park visit is a better use of a day. School-age kids through early teens generally get the most out of a visit, similar to the age range that benefits most from Ripley’s Aquarium and the Toronto Zoo.
Fitting it into a broader Toronto trip
Given the uncertainty around exact location, it’s worth treating a science centre visit as a flexible middle-of-trip activity rather than a fixed anchor for day one — see the Toronto with kids guide for how to sequence a multi-day family itinerary with one or two flexible slots built in for exactly this kind of situation.
Backup planning: don’t build a whole day around it
Given the ongoing transition, it’s worth resisting the temptation to structure an entire day of a Toronto trip around a science centre visit, particularly if you’re traveling from far away and can’t easily rearrange plans on short notice. A more resilient approach is pairing a planned science centre visit with a flexible second half of the day — a walk through downtown or time at Harbourfront both work as reasonable pivots if the science centre visit runs shorter than expected or falls through entirely due to a schedule or access change.
What families who visited recently have reported
Recent visitor accounts of interim programming generally describe a genuinely hands-on, if scaled-down, experience — favorite categories like physics demonstrations and basic chemistry stations tend to reappear in some form even at reduced scale, while larger-format exhibits and the domed theatre experience associated with the original building have generally not carried over to interim locations. Reading recent, dated reviews (rather than older ones referencing the original Don Mills building) is the most reliable way to calibrate expectations before a visit, alongside the official channels mentioned above.
Comparing the value against other Toronto attractions given the uncertainty
Weighed purely on cost versus certainty, families with limited trip time might reasonably choose to prioritize more stable attractions — Ripley’s Aquarium, the CN Tower, or Casa Loma — and treat a science centre visit as a bonus if the schedule and current operating status align, rather than a guaranteed centerpiece. This isn’t a knock on the institution’s programming quality, which by most accounts remains genuinely good; it’s simply an acknowledgment that its logistics are less predictable right now than most other entries in this family guide series.
Checking status while you’re already in Toronto
If you didn’t confirm the science centre’s status before arriving, a quick check via its official website or a call ahead from your hotel is worth doing before committing a chunk of your itinerary to the visit. This is different advice than most attractions in this family guide series warrant, but it reflects the genuinely unsettled nature of the venue’s situation right now rather than excessive caution for its own sake.
If you’re traveling with school-age kids specifically interested in science
For families whose main reason for visiting Toronto includes a kid with a strong interest in hands-on science, it’s worth treating the science centre as one option among several rather than the only one — the Art Gallery of Ontario and other Toronto cultural institutions occasionally run kid-oriented interactive programming, and it’s worth a quick search of current offerings alongside checking the science centre’s status specifically, so a single institution’s transitional situation doesn’t define the whole trip’s science-and-discovery component.
Frequently asked questions about the Ontario Science Centre
Is the Ontario Science Centre closed permanently?
No — the original Don Mills Road building closed due to structural issues, but the institution has continued operating interim programming while a new permanent facility is developed at Ontario Place. It is not a permanent closure of the institution itself.
Can I still visit the original Ontario Science Centre building?
No, the Don Mills Road building has been closed to the public since the structural issues were identified, and its future use is a separate matter from the science centre’s ongoing interim programming elsewhere.
How do I find the Ontario Science Centre’s current address?
Check the institution’s official website or official social channels directly before your visit, since interim arrangements have changed since the original closure and any secondhand guide, including this one, may not reflect the current location.
Is the interim Ontario Science Centre smaller than the original?
Likely yes — interim locations generally have less physical space than the original building’s decades of accumulated exhibits and dedicated theatre spaces, so expect a more limited but still hands-on experience.
Is it worth visiting the Ontario Science Centre if we’re only in Toronto briefly?
If confirming current hours and location works with your schedule, it remains a solid hands-on option for school-age kids; if the logistics feel uncertain given your trip timing, Ripley’s Aquarium of Canada is a more reliably stable alternative.
Will the new Ontario Place science centre be open by the time I visit?
That depends on the current state of a large public infrastructure project, which shifts over time — check current official announcements for the latest projected timeline rather than assuming a fixed date.
What else can I do nearby if the science centre visit falls through?
Harbourfront and a walk through downtown both work as flexible pivots, and the things to do in Toronto on a rainy day guide lists several other indoor backups worth having on hand regardless of the science centre’s current status.
