The worst call a property manager takes is not about the roof; it is about the roofer. When a ladder goes over at your fourplex, or a torch-down repair smoulders for six hours after the crew packs up, the question that decides who absorbs the loss is whether you verified coverage before the work started. Contractor insurance requirements landlord Canada-wide come down to three things you can check in about ten minutes: a provincial workers' compensation clearance, a general liability policy that will actually respond, and a valid licence for the trade doing the work. The trouble is that the document most owners lean on - a certificate of insurance emailed as a PDF - is the weakest of the three.
Why the hiring party wears the risk
Workers' compensation legislation in every province lets the board look up the chain when a contractor's account is in arrears. Hire a firm that has not been remitting premiums and the board can assess those unpaid amounts against you as the principal. That is not a theoretical exposure; it is the entire reason clearance certificates exist.
Liability behaves the same way. If an uninsured trade floods three units below the one they were working in, the claim lands on the building's policy. Your insurer pays, then tries to subrogate against a contractor with no policy, no assets and a numbered company that dissolves by spring. The deductible, the claims history and the renewal premium all stay with your owner.
A third exposure catches smaller landlords: if you direct a handyman's hours, supply the tools and pay them weekly, the CRA and the provincial board may both treat that person as your employee rather than an independent contractor, with payroll, CPP, EI and coverage obligations attached.
Workers' compensation is provincial: WSIB, WorkSafeBC and the rest
Ontario: WSIB clearance certificates
Coverage in Ontario's construction sector is mandatory for most independent operators, sole proprietors, partners and executive officers, not only firms with payroll. Before you issue a work order, pull the WSIB clearance certificate yourself through WSIB's online service using the contractor's legal name or account number. Do not accept a forwarded PDF; it is trivially edited and may be months stale. Each certificate carries its own validity window, so read the dates rather than assuming it spans your project.
Two Ontario traps are worth knowing. First, the home renovator exemption is narrow. It is aimed at independent operators hired directly by the person who lives in the home, so work on a rental unit arranged by a landlord or property manager generally does not qualify. Second, under the Occupational Health and Safety Act, if you engage several trades on the same project without designating a constructor, you can end up carrying constructor duties yourself: notices, supervision, and health and safety responsibility for the whole site.
British Columbia: WorkSafeBC clearance letters
BC runs on the same principle with different paperwork. Request a clearance letter through WorkSafeBC's online service instead of taking the contractor's word for it. Watch for the reply saying the firm is not registered. An owner-operator with no workers is often not required to register, which means that if they are hurt in your crawlspace they have no wage-loss coverage and every incentive to look to you. Ask whether they carry Personal Optional Protection and get it in writing.
BC also has the prime contractor rule. Where more than one employer is working at a site, the owner is the prime contractor unless the owner designates one in writing. On a two-trade bathroom job that designation is one paragraph in the contract; without it, coordination duties default to you.
Everywhere else
The mechanism is consistent even though the acronyms change: WCB Alberta, WCB Saskatchewan, WCB Manitoba, WorkSafeNB, WCB Nova Scotia, WCB PEI, WorkplaceNL, CNESST in Quebec, WSCC in the Northwest Territories and Nunavut, and the Yukon board. Each publishes some form of clearance or good-standing letter. In Quebec, add the Régie du bâtiment du Québec licence and confirm the class actually covers the work, not just that a number exists.
The contractor insurance requirements landlord Canada checklist
Run this before a crew mobilizes. It is short enough to live in your work order template:
- Commercial general liability, occurrence-based, with a limit floor you apply consistently. Many Canadian portfolios set that floor higher for roofing, hot works, excavation and structural work.
- Products and completed operations coverage. Most contractor-caused losses surface after the trade has left the site.
- Additional insured status for the owner and the management company, with a cross-liability or severability of interests clause.
- Non-owned automobile coverage (the endorsement your broker knows as SPF 6 / OAP 6). Work trucks in your parking area are a real exposure.
- Contractor's equipment or installation floater where materials sit on site before installation.
- Environmental or pollution liability for oil tank work, mould remediation, asbestos and anything touching a drain.
- Professional liability if the contractor is doing design-build or specifying an engineered fix.
- A current workers' compensation clearance for the province where the work happens, not where the contractor is headquartered.
- Trade licences and permits, including electrical contractor licensing, gas and boiler authorizations, and provincial certification. If a contractor asks you to pull the permit in the owner's name, treat it as a signal rather than a favour.
- A written contract with an indemnity clause and a no-subcontracting-without-consent clause.
What a certificate of insurance does not prove
A COI is a snapshot, not a contract. It can be accurate the day it is issued and worthless the following week if the policy lapses for non-payment. Three habits close most of that gap:
- Confirm the certificate with the broker named on it, using contact details you look up independently.
- Match the named insured to the legal entity on the quote, the invoice and the workers' compensation account. Trades often operate under a brand while the policy sits with a numbered company, and if those do not line up the policy may not respond to work billed by the other entity.
- Re-verify when the business changes. Coverage and clearance follow the legal entity, so a restructure or a sale - increasingly common as trade owners approach retirement and sell the business - can leave you holding a certificate for a company that no longer does your work.
It also helps to understand why the cheapest quote is usually the uninsured one. Premiums, comp assessments and safety programs are real line items in a contractor's rate, and the economics behind that are covered well at Construction Arbitrage. A bid that undercuts the market by forty percent is telling you which line items were skipped.
Build verification into the process, not the crisis
Check three times: at award, before mobilization on anything running more than a few weeks, and before final payment. For recurring vendors, set reminders against the policy expiry and the clearance validity window. Keep copies in the job file with the dates visible, and retain the statutory holdback your province's construction or builders lien legislation requires so an unpaid subcontractor cannot lien the property after you have paid the general in full. Tell your own insurer before major work starts, too, since renovation and vacancy conditions sit in most Canadian property policies.
This is the part marketplaces are genuinely good at. Platforms like PlanaJob let property managers compare quotes from vetted contractors side by side, so the compliance check happens before the shortlist rather than after the invoice. Every PlanaJob contractor is pre-screened for insurance and provincial workers' compensation coverage, which removes the document chase when you have a tenant without hot water. You can see how it works for property managers, create an account in a few minutes, or read more compliance guidance on the PlanaJob blog.
FAQ
Do I need a clearance certificate for a one-person handyman?
Yes, or a documented reason you do not. In construction-heavy provinces, independent operators are frequently required to register, and carve-outs such as Ontario's home renovator exemption are written for homeowners occupying the property rather than landlords with rental units. If the contractor genuinely is not required to register, ask for proof of optional personal coverage plus their own liability policy.
How much liability coverage should I require?
Set a floor and apply it to every trade instead of negotiating job by job. Ask your broker what limit your portfolio's own policy assumes contractors carry, require at least that, and raise it for roofing, hot works, height work and structural jobs. Consistency matters more than the number, because exceptions are where claims find gaps.
Am I liable if my contractor's subcontractor is injured?
You can be. Boards can pursue unpaid assessments up the chain, and where you engage several trades directly without designating a constructor in Ontario or a prime contractor in British Columbia, coordination duties may default to you as the owner. Require written consent before any subcontracting, then verify the sub's clearance and insurance exactly as you verified the general's.
