What Ontario regulations apply to eavestrough work done at heights above 10 feet?

Working at heights above 10 feet in Ontario triggers a specific set of occupational health and safety regulations that every eavestrough contractor working on your home should be following — and that you should understand before hiring anyone or attempting any work yourself.

Ontario's Working at Heights Rules for Eavestrough Work

The Occupational Health and Safety Act (OHSA) and its associated Construction Projects Regulation (O. Reg. 213/91) govern how workers must be protected when working at heights on construction sites in Ontario. For eavestrough work, the critical threshold is 3 metres (approximately 10 feet) above the ground or a lower level. Once work occurs at or above this height, contractors are legally required to implement fall protection measures. This applies directly to eavestrough installation and repair, which routinely takes place at 10 to 25 feet on typical Ottawa homes.

For eavestrough contractors, fall protection typically means one of three approaches: guardrail systems, travel restraint systems (a harness and lanyard that prevents a worker from reaching the fall edge), or fall arrest systems (a harness connected to an anchor that stops a fall after it begins). On most residential eavestrough jobs, contractors use extension ladders with standoffs combined with personal fall arrest equipment, particularly on two-storey homes where eaves can sit 18 to 22 feet above grade. Simply leaning a ladder against the fascia board without any fall protection equipment does not meet Ontario's legal standard above 3 metres.

Since April 1, 2015, Ontario has required that any worker who may work at heights above 3 metres on a construction project must hold a valid Working at Heights (WAH) training certificate issued through an approved training provider recognized by the Ministry of Labour, Immigration, Training and Skills Development. This is not optional — it is a legal requirement. When hiring an eavestrough contractor in Ottawa, you are fully within your rights to ask whether their crew holds current WAH certifications. Reputable contractors will have no hesitation providing this information.

Beyond fall protection training, WSIB (Workplace Safety and Insurance Board) coverage is essential. Eavestrough installation is classified as construction work under Ontario's WSIB system, and any contractor performing this work should carry active WSIB coverage for their employees. If an uninsured worker is injured on your property, you as the homeowner could face serious financial and legal exposure. Always ask for a WSIB clearance certificate before work begins — you can verify it directly through the WSIB website at no cost.

From a practical Ottawa perspective, these regulations matter even more because of the conditions eavestrough crews work in. Wet fascia boards, icy ground conditions in spring and fall, and awkward ladder placement around mature trees in neighbourhoods like Westboro or the Glebe all increase fall risk significantly. A contractor cutting corners on fall protection is also likely cutting corners on material quality and installation standards.

For DIY purposes, Ontario's OHSA regulations apply to workers and employers, not private homeowners working on their own homes. However, the physical risks are identical — a fall from 12 feet onto Ottawa's frozen ground or a concrete walkway can be fatal. Single-storey eavestrough cleaning with a properly footed extension ladder is a reasonable DIY task for many homeowners. Anything involving a two-storey roofline, steep pitch, or unstable ground should be left to professionals with proper equipment and training.

If you're ready to find eavestrough professionals who operate with proper safety standards, the Ottawa Construction Network directory at justynrookcontracting.com is a free resource where you can browse and contact local contractors directly. Getting at least three written quotes also gives you a chance to ask each contractor directly about their safety practices and certifications before anyone climbs a ladder at your home.
