In the context of the Ontario Building Code, the minimum number of exits required for a commercial building is determined by the occupant load, which is calculated based on the total number of people that can safely occupy the space. For a building with a capacity of 500 people, the code specifies that multiple exits are necessary to ensure safe egress in emergencies.

For an occupant load of 500, the Ontario Building Code typically requires a minimum of three exits to accommodate the potential need for evacuation and to allow for adequate dispersal of individuals during emergencies. This requirement ensures that if one exit becomes blocked or unusable, there are still alternative routes available for occupants to safely exit the building.

Furthermore, having more than one exit not only enhances safety but also helps in managing the flow of people during an evacuation, thereby reducing the risk of overcrowding at a single exit point. This requirement aligns with best practices in building safety and emergency preparedness within commercial properties.

By ensuring that a building with a significant capacity is equipped with at least three exits, the building code helps to maintain a high standard of safety for all occupants.
