Construction payroll in Canada: manage compliance on every job site.
Canadian construction payroll hits about a quarter of revenue. Compliance burden, multi-site pay, and trades-specific rules make it one of the most demanding payroll environments in the country.
Quick answers
What makes construction payroll in Canada complex?
Construction payroll involves multi-jurisdiction work, prevailing-wage and union rules, WSIB or WCB classifications, and T5018 contractor reporting. Payroll Cashback is an independent consultant that connects construction firms with 10 or more employees, across Canada outside Quebec, to a payroll partner equipped for these requirements.
Construction operators carry about twenty-five percent of revenue in payroll. That alone is a lot of overhead. Add workers compensation, union rules, and multi-province jobs, and payroll becomes a compliance job on top of a labour cost.

Why construction and trades payroll is hard
Multi-site and multi-province complexity
Running crews across provinces compounds source-deduction, WCB, and reporting obligations.
Workers compensation is material
WCB premiums are a real line item. Errors in classification cost money and attention.
Unpredictable overtime
Weather, scope changes, and deadlines mean overtime happens. Payroll systems built for predictable schedules buckle.

Frequently asked questions
What workers compensation rules apply to construction payroll in Canada?
Construction employers in Canada must register with the provincial workers compensation board in each province where they employ workers. Ontario's WSIB, Alberta's WCB, and BC's WorkSafeBC all assign construction rate codes with premium rates that reflect the risk profile of construction work. Rates vary by trade, site type, and employer experience rating. Multi-province construction operators must maintain separate registrations and premium accounts in each province. Misclassifying workers between rate groups is the most common audit finding in construction payroll.
How is subcontractor versus employee classification determined in Canadian construction?
CRA applies a four-factor test to determine whether a construction worker is an employee or an independent contractor: control over the work, ownership of tools, chance of profit, and risk of loss. In construction, subcontractors who work exclusively for one general contractor, use contractor-supplied equipment, and follow contractor-set schedules typically fail the test and are reclassified as employees. The consequences include retroactive source deduction assessments, CPP and EI back-contributions, and potential director liability. Construction companies using subcontractor structures should have their classification reviewed by a payroll specialist outside Quebec.
How is overtime calculated for construction workers in Canada?
Overtime rules for construction workers vary by province. In Ontario, construction industry workers are generally exempt from the 44-hour weekly overtime standard under the Employment Standards Act 2000 if covered by a collective agreement that addresses overtime. In Alberta, overtime applies after 8 hours daily or 44 hours weekly, with averaging arrangements available. In BC, overtime applies after 8 hours daily or 40 hours weekly. Federally regulated construction projects follow the Canada Labour Code. A construction payroll specialist handles these province-specific thresholds correctly for each site and each worker.
How does union payroll work in Canadian construction?
Union construction payroll operates under collective agreements that specify wage rates, overtime rules, shift premiums, vacation pay, and benefit plan contributions. Union payroll requires remitting contributions to benefit plans, pension plans, and union dues according to collective agreement schedules in addition to standard CRA source deductions and provincial WCB premiums. The administrative complexity is substantially higher than non-union payroll, and errors in benefit plan remittances can trigger union grievances. A payroll partner experienced in union construction payroll handles collective agreement compliance as part of the service.
How can a PEO help a Canadian construction company with payroll?
A PEO handling construction payroll manages source deduction calculation and remittance to CRA, provincial WCB registration and premium remittances across each province of operation, worker classification documentation to reduce audit exposure, multi-site hour tracking for provincial employment standards, and T4 year-end issuance. For construction operators running projects across Ontario, Alberta, and BC simultaneously, the PEO handles the multi-province compliance work as part of the core service. This service is available to Canadian construction companies with 10 or more employees outside Quebec.
