Scaffolding is a working-at-heights trade, and in Canada fall protection is the centre of gravity for the whole job. There is no single national licence to erect scaffold, and whether scaffolder is a compulsory or voluntary trade varies by province, but the occupational-health-and-safety law on heights is the same idea everywhere: once a worker can fall a set distance (3 metres, about 10 feet, is the common threshold), fall protection is mandatory, and scaffold itself must be erected, inspected and tagged by competent people. Get the heights and scaffold-erector certification sorted before you take a single job, because the regulator and every general contractor will check it.
Licensing: heights certification first, trade status varies
There is no countrywide "scaffolder licence", but there are two things you cannot skip:
- Working-at-heights / fall-protection training. Every province requires fall protection once a worker is exposed to a fall of about 3 metres (10 feet) or more (the exact trigger height is set in each province's OHS regulation, and Ontario, for example, mandates an approved Working at Heights training program for workers on construction projects). This training is the baseline, it expires, and it must be current.
- Scaffold erector competency. Scaffold must be erected, altered, inspected and dismantled by a competent worker, and inspected and tagged before use and at intervals set by the regulation. Many provinces and large industrial sites require a recognised scaffold-erector certification (for example through a union training centre or an accredited provider).
On the trade side, scaffolder exists as a certifiable trade in some provinces (and is a designated trade in parts of Canada), but it is not uniformly compulsory, so the status varies; the heights and scaffold-erector certification matter more for getting on site than the formal trade ticket in most regions. Quebec runs its own system: scaffold work falls under the Commission de la construction du Quebec (CCQ) competency regime under R-20, and the contractor needs an RBQ licence. Confirm your province's exact requirements.
Fall protection: the rule the trade turns on
This is the part to get right, because it is what the inspector and the safety record turn on:
- The trigger height. Fall protection is required once exposure to a fall of about 3 metres (10 feet) exists; some settings and provinces set it lower, so use the lower of the applicable thresholds.
- The hierarchy. Guardrails first, then travel-restraint, then a fall-arrest system (full-body harness, lanyard, shock absorber and an adequate anchor) where guardrails are not practicable.
- Scaffold standards. Scaffold must be built to the applicable standard (CSA standards and the provincial OHS scaffold rules), be fully planked and guarded, sit on adequate base plates and mud sills, be tied in as it rises, and be tagged with its inspection status (a common green / yellow / red tag system) before anyone works from it.
- Inspection. A competent person inspects the scaffold before first use, after any alteration, and at regular intervals, and records it.
Kit and start-up costs (estimates, CAD)
A scaffolder starting as a subcontractor needs PPE, fall-arrest gear and, eventually, scaffold stock, which is the big variable; many start by labouring or subcontracting before owning material. Indicative ranges, so confirm current prices:
- Full-body harness, lanyards, shock absorber and connectors (per worker): roughly $300 to $800.
- Fall-protection and scaffold-erector training: roughly $300 to $1,500 depending on the courses and province.
- Hand tools (scaffold ratchets, levels, podgers): roughly $500 to $1,500.
- PPE (hard hat, safety boots, gloves, hi-vis): roughly $500 to $1,000.
- CGL insurance: roughly $2,500 to $6,000 per year, and proof is required by general contractors.
- Scaffold stock (frames, tubes, boards, fittings): the major cost if you own material, easily tens of thousands of dollars, so renting at first is common.
What you can charge or earn (estimates, not fixed rates)
There is no single published national rate table, and scaffold pricing depends on access, height, duration and whether you supply material, so treat these as indicative ranges, not fixed figures:
- Employed or subcontracted scaffolder hourly rates: roughly $30 to $55 per hour, higher on union industrial agreements.
- Erect-and-dismantle pricing to a client: usually quoted per job or per square metre of access, plus a weekly hire charge while the scaffold stands; price the access and the standing time, not just the labour.
Industrial and shutdown scaffold work pays premiums but is intermittent. Confirm your numbers against the union local and local competitors.
Common mistakes
- Letting working-at-heights training expire. It is time-limited; an expired certificate means no site access.
- Working from an untagged or un-inspected scaffold. The tag and the competent-person inspection are mandatory; an untagged scaffold is a stop-work.
- Skipping the anchor calculation. A harness is useless without an adequate, rated anchor; clipping to the wrong point fails when it matters.
- Forgetting GST/HST. Once your taxable revenue passes $30,000 over four consecutive quarters (or in a single quarter), you must register for GST/HST within 29 days of the effective date.
