Ontario Occupancy Load Signs — Requirements for Businesses
Share
If your Ontario business has a room, hall, or area used for assembly purposes, you likely need an occupancy load sign. The Ontario Fire Code is clear: the maximum number of people allowed must be posted — and exceeding it is an offence.
Who Needs Occupancy Signs?
Any room or area classified as an assembly occupancy under the Ontario Building Code:
- Restaurants — dining rooms, banquet halls, patios
- Bars and nightclubs
- Churches and community halls
- Gyms and fitness centres (gym sign requirements)
- Conference/meeting rooms
- Retail stores (large floor areas) (retail sign requirements)
- Hotels — ballrooms, conference rooms (hotel sign requirements)
- Schools — gyms, auditoriums, cafeterias
- Theatres and cinemas
- Daycares (daycare sign requirements)
How Occupancy Load Is Calculated
The Ontario Building Code uses floor area per person to determine maximum occupancy:
| Use Type | Area Per Person | Example |
|---|---|---|
| Standing (no fixed seats) | 0.4 m² / person | Dance floor, standing bar |
| Seated at tables | 0.95 m² / person | Restaurant dining room |
| Fixed seating | Count the seats | Theatre, auditorium |
| Classroom | 1.85 m² / person | Training room, studio |
| Exercise room | 9.3 m² / person | Yoga studio, gym floor |
Example: A 200 m² restaurant dining room: 200 ÷ 0.95 = 210 persons maximum.

FAQ
Who determines the occupancy load?
The OBC determines it based on floor area and use type. Your local fire department or building inspector confirms the official number.
Can I calculate my own occupancy load?
You can estimate using OBC tables, but get official confirmation from your local fire department as exits and other factors may reduce the maximum.
Do I need a separate sign for each room?
Yes. Each assembly area needs its own sign at its entrance(s).
