What to Bring

You’re welcome to bring birthday cake, candles and loot bags to personalize your party.


You can bring snacks and cold "finger" foods with you to your party. A standard-sized fridge and freezer are available to store regular or ice cream cakes. Upon arrival, a party staff member will store your cake for you until serving time.

Please do not bring sparklers or trick candles, as these may cause the fire alarm to activate.


The party room is bright and cheerful, and your package includes themed table décor items as well as colour-coordinated partyware (plates and napkins). Tied or weighted balloon trees may be brought to your party (they must be inflated in advance). For safety reasons, piñatas are not permitted at the Ontario Science Centre. We are not able to provide early access to the party rooms for decoration or other personalized set-up.

Parking and Check-In


Discounted parking of $6 (50% off) is available for all Birthday Party guests. Be sure to provide the parking attendant with the name of the birthday child to receive the discounted rate. Vehicles may pull into the drop-off loop to drop off party guests before parking.


Please arrive 20 minutes prior to your scheduled party time. Please use the front entrance and have your group follow the “Happy Birthday” signs to the Birthday Party Welcome Centre In the lobby. Your Party Staff will be awaiting your arrival. Please note: All parties start and end on time.

Late Guests

Guests arriving late must check-in at the Membership Desk inside the front entrance and provide the birthday child's name to the Desk Attendant. A Party Staff member will be called to escort them to your party.

Frequently Asked Questions

What if the Birthday Party package doesn’t meet my needs?

Birthday Party packages are carefully created and cannot be altered or customized. Looking for a more personalized party event? Please contact our Facility Rentals department at 416-696-3146 to discuss room rental opportunities and catering options..

What if my child has siblings or guests who are under 5 or over 8 years old?

The Birthday Party activities are designed with specific age groups in mind. As such, we strongly recommend choosing a theme based on the age of the birthday child and most of their guests. Party guests who fall outside the 5–8 year age range will still have a great time!

Are discounts permitted?

No additional coupons, passes, membership cards/benefits, discounts or vouchers can be applied in place of payment for Birthday Party fees, add-ons or extra children or adults attending the party.

How many adults are required at the party?

A minimum of one adult is required per party, but up to 13 adults are welcome to attend. Please consider the group size and age of the children when determining how many adults should attend to safely manage your group.

Can I add extra guests to my booking?

Yes. All Birthday Party packages allow additional adult and child guests. Up to nine additional children and three additional adults may be added to the Birthday Party package at a cost of $25/person.

Any extra adults over the party maximum are welcome to purchase a general admission ticket and explore the Science Centre until the Birthday Party is over.

How do I add extra guests?

Please call 416-696-3256 to add children and/or adults to your booking. Please confirm your final numbers for attendance and food orders by 4 p.m. on the Wednesday prior to your Birthday Party.

What if extra children show up at the last minute that I didn’t include in my Birthday Party numbers?

Party resources and activities are prepared based on the confirmed number of expected party guests, so it’s important that you provide an accurate count. However, in the unexpected event that extra children show up, we will do our best to accommodate them provided the group size does not exceed the maximum of 20 children. The credit card used to book your party will be charged the applicable amount for each additional guest.

Are guided tours of the Science Centre available before or after the Birthday Party?

Exploration of our exhibit halls is self-guided. There are Hosts on the floor who are happy to help and answer questions, but we do not offer guided tours. When visiting the Science Centre, please ensure you are able to adequately supervise the children in your group.

What if my child is sick and I have to cancel my party? Is my payment refundable?

If your child is sick on the day of the party, please contact us. We will work with you to reschedule the party at no additional cost. If there are no alternate party times available, we will grant a refund if you provide a written request and a doctor's note within one week of the missed party. Cancellations received 14 days or more prior to the Birthday Party date are fully refundable, less a $70 administration fee. For last-minute cancellations, please inform Party Staff at 416-696-3256.

Do you provide loot bags?

We do not provide loot bags. You are welcome to bring your own.

Do I need to clean up the Birthday Party room?

Leave the party preparations and clean-up to us! Relax and enjoy the party with your child and guests.
