Retirement home payroll: staffing a building that never closes

Weekly overtime, rotating shifts, and averaging

Ontario overtime is triggered by the week, not the shift: time and a half after 44 hours in a work week, so a 12-hour shift creates no overtime by itself. What trips residences is the rotation — a continental pattern that alternates light and heavy weeks generates overtime in the heavy week unless a written averaging agreement, over periods of up to four weeks, smooths the count. The daily rules still stand on their own: eleven consecutive hours free from work each day, and eight hours between shifts unless the two together run 13 hours or less.

Shift premiums are the quiet multiplier. Night and weekend differentials are wages, so they raise the regular rate that overtime is calculated on, flow into public-holiday pay through the averaging formula, and accrue vacation pay. A differential coded as a discretionary bonus outside those calculations is an underpayment repeated every pay period.

Public holidays in a home that cannot close

Care staff work Christmas, and because a residence is a continuous operation it can schedule them to — the question is which of the two lawful treatments each employee gets:

The formula matters in care because rosters vary. An aide who carried heavy weekend shifts in the prior four weeks earns more holiday pay than her base rate suggests — and payroll software only gets that right when premiums sit in the earnings codes the formula reads.

Everyone inside the building is probably yours

A residence has almost no defensible contractor roles on the floor. Aides, servers, housekeepers, activity staff, and cooks work your schedule, in your building, with your equipment — employment on every factor CRA weighs, so they belong on T4s with full source deductions. The genuine outsiders are the visiting professionals: the hairdresser renting the salon chair, the physiotherapist billing residents directly, the entertainer invoicing per event. The test is who controls the work and who carries business risk, and inside a staffed building that answer rarely favours contractor status.

Agency top-ups cost more than the invoice

An agency-filled shift carries three costs beyond the bill rate. First, HST: staffing services are taxable, and because a residence's core supplies are HST-exempt there is no input tax credit — the tax is a real 13% premium on every agency hour in Ontario. Second, liability: under the ESA, a client business is jointly and severally liable for an assignment employee's unpaid regular wages, overtime, and public-holiday entitlements, so the agency's payroll failures can become yours. Third, licensing: temporary help agencies have required an Ontario licence since January 1, 2024, and knowingly using an unlicensed one is itself a contravention — the licence check belongs in your vendor file.

Priced honestly — bill rate, plus unrecoverable HST, plus risk — agency hours usually lose to overtime for your own staff or a properly built casual pool. Making that call takes a fully loaded internal cost per hour, which is exactly what the departmental cost centres in our retirement home bookkeeping produce each month.

The rest of the roster file

Headcount makes the routine items material. Employer-paid group life premiums are a taxable benefit while health and dental generally are not, so the benefit codes need to be right across a large roster. A staff member who lives on site has board and lodging valued and reported on the T4. Deductions from wages need written authorization and can never cover breakage or shortages. And thresholds arrive on their own schedule as payroll grows: remittance frequency accelerates with average monthly withholding, and Ontario's Employer Health Tax applies once payroll passes the $1 million exemption.

Turnover paperwork is constant — ROEs within five calendar days of an interruption, T4s for the full roster by the end of February, WSIB classifications confirmed for care and non-care roles. If your ownership group has US investors or a US operator relationship, payroll is not where that shows up; the honest version of that file lives on our retirement home cross-border tax page.
