DRAFT. Part of the Ontario daycare resource hub. Ratios decide your staffing costs and room layouts — here's the full reference. [VERIFY all figures against current O. Reg. 137/15.]
Ratios & maximum group sizes
| Age group | Ratio (staff:children) | Max group |
|---|---|---|
| Infant (under 18 mo) | 3:10 | 10 |
| Toddler (18–30 mo) | 1:5 | 15 |
| Preschool (30 mo–before grade 1) | 1:8 | 24 |
| Kindergarten | 1:13 | 26 |
| Primary/Junior school-age | 1:15 | 30 |
Space per child
Minimum 2.79 m² (30 sq ft) of unobstructed indoor play space per child, plus outdoor requirements [VERIFY]. This caps how many children a room can hold regardless of ratio.
What ratios mean for your build
Group-size caps determine how many of each furniture piece you need per room — plan your room setup around them. Ratios also feed your licensing staffing plan.
