I have been to the Ontario Science Centre many times. First yelp review. This is a great place to bring your kids to spend the whole day here. They learn a lot and there's lots of great activities to keep them busy. You can buy tickets cheaper at Costco. Also an annual membership is worth it if you come a lot. It's includes entrance fee for 2 adults and 6 kids! Plus half price parking. Parking is $10 regularly. There are a few floors packed with great shows and activities for the kids. Also there's a food area where there's pasta, pizza, salad and hamburgers. Lots of variety. If you have a membership card you can use it for an additional 20% off the food there in the food court. Seats are very limited especially during the holidays and weekends. The 4th floor is my girls favourite with a cool supermarket where the kids can buy food as well as a farm right next to it. There's a water play area and a construction area. Very cool.
