Hearing clinic payroll: two clinical roles, two pay structures

Audiologists and hearing instrument specialists are not the same payroll line

CASLPO-registered audiologists hold a regulated health credential. That typically puts them on T4 salary if employed, or on shareholder compensation if they own the professional corporation. Hearing instrument specialists dispense and fit hearing aids under a separate registration track. They are more often paid a base plus a per-unit or percentage commission tied to device sales. We keep the two on separate pay structures in the same payroll run. Treating a commissioned dispenser like a salaried professional — or vice versa — creates ESA and source-deduction problems neither role should have.

Commission pay has its own Employment Standards Act mechanics

Ontario's ESA treats commission employees differently from salaried ones for overtime, vacation pay, and termination calculations. A hearing clinic's commission is usually tied to unit sales net of returns inside the trial period. That means a commission earned in one pay period can be clawed back if the device comes back a few weeks later. We track commission on a per-sale basis against the trial-return calendar, so clawbacks are applied correctly rather than guessed at. Vacation pay is calculated on the commission actually earned, not the gross device price before any refund.

• Base plus commission split — the base is run as regular salary; the commission layer is calculated separately each pay period against confirmed, non-returned sales.
• Front-desk and scheduling staff — usually hourly, with their own vacation accrual and stat holiday pay calculation under the ESA.
• Associate audiologists — an audiologist may work under a room-and-referral arrangement rather than as an employee. We help confirm whether that relationship is genuinely a contractor split or an employment relationship the CRA would recharacterize. See how the CRA decides employee or contractor status.

WSIB is not optional once fitting work is involved

Hearing clinics with employees are generally required to carry WSIB coverage. Clinics that also run repair benches, mobile testing units, or offsite ADP assessments should confirm every location and role is captured under the account. A technician doing home visits for elderly ADP clients is still a covered worker. We set the WSIB premium calculation up against actual insurable earnings, including the commission component for hearing instrument specialists. That way, the year-end reconciliation does not surface an underpayment months after the fact. A clinic running two or three locations often shares a technician across sites on a fixed weekly rotation. We track hours and commission by location as well as by employee. That way, a multi-site owner can see which clinic is actually carrying the payroll cost rather than relying on one blended number.

Part-time repair-bench coverage and casual front-desk staff bring their own vacation-pay accrual and Employer Health Tax calculation. That is common in a business built around scheduled appointments rather than walk-in retail volume. We set the EHT calculation up once against the exemption threshold available to eligible private-sector employers, rather than recalculating it by hand at each remittance. We then reconcile it against the WSIB premium base, so the two do not drift apart over the year.

Owner-audiologists: salary, dividends, or both

Where the clinic operates through a professional corporation, the owner-audiologist's own pay is a planning decision, not a payroll default. A T4 salary builds RRSP room and CPP contributions and supports a mortgage application. Dividends skip both CPP and RRSP room but leave more cash inside the corporation for equipment and inventory financing. Most owner-audiologists land on a blend. We revisit the split each year against the corporation's cash position. A clinic financing a new sound booth or a bulk device order in a given year often prefers to lean toward dividends that year. It adjusts back once the purchase is behind it.

Cross-border staff are rare, but not unheard of

Occasionally a clinic brings in a US-trained AuD on a work permit before Canadian registration is complete. Other times, a manufacturer's US-based clinical trainer runs an in-clinic session. Payments to a non-resident individual for services performed in Canada can trigger Regulation 105 withholding, regardless of how the invoice is styled. That is why we flag any US-based trainer or locum before the first cheque goes out rather than after. The clinic owner may have their own cross-border history: a US audiology degree, US loans, US retirement accounts. Our cross-border tax page for hearing clinics covers that personal side. This page covers what shows up on the clinic's own payroll.
