Cable railings have become increasingly popular in Canada due to their modern aesthetic and ability to provide unobstructed views. However, before installing such systems, it's crucial to understand the legal and safety regulations that govern their use across the country.

National Building Code (NBC) Guidelines
The National Building Code of Canada (NBC) 2015 permits the installation of horizontal cable railings under specific conditions:
- Height Restrictions: Horizontal elements that could facilitate climbing are allowed if the guard protects a level less than 4.2 meters (13' ¾") above the adjacent level.
- Opening Limitations: Openings in the guard must prevent the passage of a 100mm (4") diameter sphere.
It's important to note that while the NBC provides a national framework, building codes are enforced at the provincial and municipal levels, which may have additional requirements.
Provincial Regulations and Variations
While many provinces have harmonized their building codes with the NBC 2015, there are notable exceptions:
- Ontario: The Ontario Building Code prohibits horizontal railings for decks, ramps, or stair guards, requiring vertical elements unless the platform is less than 36 inches above grade.
- Quebec: Adopted the NBC 2015 with amendments in 2022, allowing horizontal cable railings under the same conditions as the NBC.
- Other Provinces: Provinces like British Columbia, Alberta, and Nova Scotia have adopted the NBC 2015, permitting horizontal cable railings with adherence to specified guidelines.
Always consult local building authorities to ensure compliance with regional regulations before installation.
Installation Requirements for Compliance
To ensure that a cable railing system complies with Canadian building codes, consider the following installation requirements:
1. Post and Cable Spacing
- Post Spacing: Posts should be spaced no more than 4 feet (1.2 meters) apart to minimize cable deflection.
- Cable Spacing: Cables should be spaced to prevent a 4" sphere from passing through, typically requiring spacing of 3" or less.
2. Cable Tension and Material
- Tension: Cables must be properly tensioned to prevent sagging and maintain safety standards.
- Material: Use stainless steel cables (e.g., 1/8" 7x7) for durability and corrosion resistance.
3. Handrail Requirements
- Height: Handrails should be between 865mm and 1070mm (34" and 42") above the nosing of stairs.
- Graspability: Handrails must be graspable, allowing users to securely hold them for support.
