Reviewed by Calculator Editorial Team

Determine the maximum occupancy for your store in Ontario based on square footage, fire codes, and health regulations. This calculator helps business owners, facility managers, and real estate professionals comply with Ontario's store capacity requirements.

How to Use This Calculator

Using the store capacity calculator is simple:

  2. Select the type of store (retail, warehouse, etc.)
  3. Choose whether the store has fixed seating or flexible seating
  4. Click "Calculate" to see the maximum allowed occupancy

The calculator will display the recommended maximum capacity based on Ontario's regulations and your store's characteristics.

Formula Used

Store Capacity Formula

The maximum store capacity is calculated using:

Capacity = (Square Footage × Occupancy Factor) ÷ Area per Person

Where:

  • Square Footage = Total floor area of the store
  • Occupancy Factor = Percentage of usable space (varies by store type)
  • Area per Person = Minimum square footage per person (varies by Ontario regulations)

The calculator uses Ontario-specific occupancy factors and area per person values based on the type of store and seating arrangement.

Worked Example

Let's calculate the capacity for a 2,000 sq ft retail store with fixed seating:

  1. Square Footage = 2,000 sq ft
  2. Occupancy Factor (retail store) = 80%
  3. Area per Person (fixed seating) = 10 sq ft

Calculation:

Capacity = (2,000 × 0.80) ÷ 10 = 160 people

Therefore, the maximum capacity for this retail store is 160 people.

Ontario Store Capacity Regulations

Ontario's Occupational Health and Safety Act (OHSA) and Fire Code regulations establish minimum standards for store capacity. Key points include:

  • Minimum square footage per person varies by store type and seating arrangement
  • Retail stores typically require 10-12 sq ft per person
  • Warehouses may have higher requirements (15-20 sq ft per person)
  • Flexible seating allows for higher capacity than fixed seating
  • Occupancy factors account for non-usable space like aisles and restrooms

Important Note

These are minimum requirements. Actual capacity may be higher if your store meets additional safety standards.
