Toddler open play in Ontario: practical notes
- Go weekday mornings if you can. It's the calmest window at most indoor playgrounds, and venues that run toddler-only hours usually schedule them then — check each listing's hours, or call.
- Pack grip socks. Most venues require them for walkers; many sell them at the door if you forget.
- Ask about pre-walker pricing. Some venues discount or waive admission for crawlers — policies vary, so it's worth the 30-second call.
- Look for the gate. The point of a toddler zone is that bigger kids can't run through it. If you visit and the "toddler area" is just a corner of the main floor, weekday mornings matter even more.
