Passive fire protection spray foam in Ontario provides critical fire resistance for commercial and residential structures, with intumescent coatings offering up to 4-hour fire ratings at costs ranging from $8-15 CAD per square foot. These specialized fireproofing systems expand when exposed to heat, creating an insulating char layer that protects structural steel and other building components according to Ontario Building Code requirements under Division B Part 3.
What Is Passive Fire Protection Spray Foam and How Does It Work?
Passive fire protection spray foam consists of intumescent coatings that react to heat by expanding up to 50 times their original thickness. When temperatures reach approximately 200°C, the coating begins to intumesce, forming a thick, insulating char layer that protects the underlying substrate. This process provides crucial fire resistance without requiring active systems like sprinklers or alarms.
In Ontario, these systems must comply with CAN/ULC standards and provide specific fire resistance ratings (FRR) based on building occupancy and height requirements. The most common applications include structural steel protection, where intumescent spray fireproofing provides essential protection for commercial buildings, warehouses, and multi-story residential developments throughout Etobicoke and the Greater Toronto Area.
What Are the Ontario Building Code Requirements for Passive Fire Protection?
The Ontario Building Code mandates specific fire resistance ratings based on building classification, occupancy type, and structural elements. Part 3 buildings (typically commercial and industrial structures) require fire resistance ratings ranging from 45 minutes to 4 hours, depending on the application.
Key requirements include:
- Structural steel members supporting more than one floor: minimum 2-hour FRR
- Columns in Group A, B, or F occupancies: 1-4 hour FRR depending on building height
- Floor assemblies in high-rise buildings: minimum 2-hour FRR
- Mechanical and electrical penetrations: appropriate fire stopping systems
Property owners in Etobicoke must ensure compliance through proper installation and regular fireproofing inspections to maintain valid building permits and insurance coverage.
How Much Does Passive Fire Protection Spray Foam Cost in Ontario?
Passive fire protection spray foam costs in Ontario typically range from $8-15 CAD per square foot for standard applications, with pricing varying based on fire rating requirements, substrate type, and project complexity. Commercial fireproofing projects often see economies of scale, with larger applications reducing per-square-foot costs.
Cost breakdown for common applications:
- 1-hour fire rating: $8-10 CAD per square foot
- 2-hour fire rating: $10-12 CAD per square foot
- 3-4 hour fire rating: $12-15 CAD per square foot
- Complex geometries or confined spaces: additional $2-5 CAD per square foot

What Types of Buildings Require Passive Fire Protection in Etobicoke?
Etobicoke’s diverse building stock requires passive fire protection across multiple property types. Commercial buildings, industrial facilities, multi-unit residential developments, and institutional buildings all fall under specific Ontario Building Code requirements for fire resistance.
Common applications include:
- Office towers and commercial complexes along major corridors like The Queensway
- Manufacturing and warehouse facilities in industrial zones
- Condominium developments and apartment buildings
- Educational facilities and healthcare buildings
- Retail and hospitality structures
Each building type has specific requirements based on occupancy load, building height, and structural design. Commercial fireproofing applications often require the highest fire resistance ratings due to occupancy density and evacuation challenges during emergency situations.

Frequently Asked Questions
How long does passive fire protection spray foam last?
Properly installed intumescent coatings typically provide 15-25 years of service life with regular inspection and maintenance. Environmental factors and building conditions affect longevity, making periodic assessment important for continued compliance.
Can passive fire protection be applied to existing buildings?
Yes, retrofit applications are common during renovations or building upgrades. Existing structures may require additional surface preparation and compatibility testing to ensure proper adhesion and performance of new fireproofing systems.
What maintenance is required for intumescent fire protection systems?
Routine visual inspections every 12-24 months identify potential damage from mechanical impact, weathering, or coating degradation. Professional assessment determines if touch-up repairs or reapplication is necessary to maintain fire resistance ratings.
Does passive fire protection affect building insulation performance?
Intumescent coatings provide minimal thermal insulation under normal conditions but do not interfere with building envelope insulation systems. Some formulations offer slight energy benefits, but primary function remains fire protection rather than thermal performance.
