Optometry payroll: associates, dispensary commissions, and the OPC's share rules

The associate OD: per-diem, percentage, and what the facts say

An associate optometrist's status turns on control and risk, not on how the cheque is calculated. An associate paid a per-diem for set clinic days, on your booking system, your equipment, and your recall list, shows most of the markers of employment — the per-diem label does not change that. A percentage-of-billings associate who sets their own schedule, carries their own College of Optometrists registration and liability coverage, and works at other practices has a genuine claim to self-employment.

The paperwork follows: employees go on payroll with a T4 and full withholding; a self-employed associate paid personally gets a T4A with fees in box 048, and one billing through their own health-profession corporation just invoices you. Guessing wrong is expensive in both directions — retroactive CPP and EI for the practice, denied expenses for the associate — so we document the call before the first cheque, not after a ruling request.

Dispensary commissions are retail wages

Commission on frames, lenses, and contacts is the standard way to drive optical sales, and every dollar of it is wages. That means source deductions, insurable and pensionable earnings, and two follow-on effects that surprise practices used to thinking of themselves as clinics:

The design test is simple: the plan must compute from numbers your point-of-sale already produces. A commission scheme that needs a spreadsheet debate each month generates payroll errors and resentment in equal measure.

Opticians, optical assistants, and one roof with two schedules

Dispensary staff split into registered opticians — licensed by their own college, often paid more, sometimes commissioned — and optical assistants and pre-testers, who are hourly. Cross-training blurs the lines in a way payroll has to track: a staffer doing pre-test in the morning and selling frames in the afternoon works one set of hours, and overtime lands after 44 combined hours in the week even if each role alone stays under. Keep real time records by role, both for overtime and because commission eligibility usually attaches to floor hours only. Saturday hours are normal in optical retail, and Ontario imposes no automatic weekend premium — but a consistent written schedule keeps public-holiday eligibility and the pay formula clean when a stat lands on your busiest day.

Paying yourself from the OPC — without the family option

Ontario restricts shares of an optometry professional corporation to members of the College of Optometrists. The carve-out that lets physicians and dentists issue non-voting shares to family does not extend to optometrists, so dividend income-splitting is structurally unavailable — there is no share for a spouse to hold, and TOSI never even gets asked. The only defensible family channel is salary for real work at a market rate, documented and run through payroll with a T4.

Your own pay is the familiar modelling question with an optometry twist: the practice's retail profits and its professional fees land in the same corporation, and the salary-versus-dividend blend should reflect cash needs, RRSP room, and CPP — the employer share of which the OPC bears on any salary, including the CPP2 band above the first earnings ceiling. We revisit the mix annually alongside the practice's tax planning rather than letting last year's choice repeat by default.

The rails, and the border

Mechanically the practice needs an RP account under the OPC's business number, cloud payroll such as Wagepoint, remittances by the 15th of the following month, T4s by end of February, and prompt ROEs — retail-side turnover makes those routine. If you trained in the US, still carry US student loans, or buy dispensary equipment from US vendors, none of it touches payroll, but it does need a plan; that side lives in our cross-border guide for optometrists.
