Capacity Limit Calculator Ontario

This capacity limit calculator helps you determine the maximum number of people allowed in Ontario workplaces, events, and public spaces according to current provincial health and safety regulations. The Ontario government updates these limits regularly based on public health recommendations.

How to Use This Calculator

To calculate the capacity limit for your Ontario location:

Select the type of establishment from the dropdown menu
Enter the total square footage of the space
Specify the occupancy type (indoor or outdoor)
Click "Calculate" to see the maximum allowed capacity

The calculator uses current Ontario government guidelines which may change without notice. Always verify with local health unit regulations before planning an event.

Formula Used

The Ontario capacity limit is calculated using the following formula:

Capacity Limit = (Square Footage ÷ Occupancy Factor) × Safety Factor

Where:

Square Footage = Total area of the space in square feet
Occupancy Factor = Government-approved factor for the establishment type
Safety Factor = 0.8 (standard reduction for safety margins)

The Occupancy Factor varies by establishment type as defined by the Ontario government. For example:

Establishment Type	Occupancy Factor
Retail Store	10 sq ft/person
Restaurant (seated)	8 sq ft/person
Gym	12 sq ft/person
Conference Room	6 sq ft/person
Outdoor Event	15 sq ft/person

Worked Examples

Example 1: Restaurant Capacity

For a 500 sq ft restaurant with seated dining:

Capacity Limit = (500 ÷ 8) × 0.8 = 50 people

This means the restaurant can accommodate up to 50 seated customers while following Ontario health regulations.

Example 2: Outdoor Event Space

For a 2,000 sq ft outdoor event space:

Capacity Limit = (2,000 ÷ 15) × 0.8 = 107 people

The event can safely accommodate up to 107 people according to current guidelines.

Exceeding capacity limits can result in fines, temporary closures, or legal action. It's important to follow all Ontario health and safety regulations to avoid penalties.

Are outdoor events subject to the same limits as indoor spaces?

Outdoor events generally have higher capacity limits due to better ventilation and spacing requirements. The calculator accounts for these differences in the occupancy factors.

Can I adjust the safety factor in the calculation?

The safety factor of 0.8 is a standard reduction applied to all calculations. While you can modify it, it's recommended to use the government-approved value to ensure compliance.
