Incorporating an optometry practice: the OPC and the dispensary question
An optometry professional corporation earns its keep twice: the roughly 12.2% small-business rate on retained profit, and a clean home for a practice that is half health care, half retail. The structural decision that matters most is where the dispensary lives — inside the professional corporation as part of your practice, or in a separate company with different ownership rules.

The math when half your revenue is retail
An optometry practice is really two businesses — insured and private-pay eye exams, plus a dispensary selling frames and lenses — and incorporation serves both. Profit retained in the corporation is taxed at about 12.2% up to $500,000, versus personal rates above 50%, and that spread finances frame inventory, an OCT or upgraded pre-testing equipment, and the second exam lane. The dispensary actually strengthens the case beyond most health professions: inventory and fit-out consume cash, and low-taxed retained earnings are the cheapest way to fund them.
An associate paid per diem with no inventory to carry has a thinner case. Incorporate when ownership, retained profit, or a practice purchase is in view — not before the compliance costs earn their keep.
What your college requires of an OPC
An optometry professional corporation is an Ontario (OBCA) corporation authorized by the College of Optometrists of Ontario, with a name following the College's professional-corporation style and articles restricting it to the practice of optometry and related activities. Like most regulated professions — and unlike physicians and dentists — shares must generally be held by licensed optometrists. There is no family non-voting class, so income-splitting plans built on family shareholders do not transfer here; confirm your college's current rules before issuing a single share.
The corporation never shields you from professional negligence claims either — that protection stays with insurance. What it does contain are leases, suppliers, and financing. Dispensing prescription eyewear is ordinarily part of an optometric practice, so most ODs run the dispensary inside the OPC. Whether it should stay there is a genuine decision.
One corporation or two: where the dispensary lives
| Decision point | Dispensary inside the OPC | Separate retail corporation |
|---|---|---|
| Ownership | Licensed optometrists only | Open — a spouse, an optician partner, an investor |
| Admin | One set of books, one T2 | Two corporations, cost allocations, an intercompany agreement |
| HST | One registration covers exempt, zero-rated, and taxable streams | Each entity's registration assessed on its own sales |
| At sale | Exam practice and dispensary goodwill move together | Retail side can be sold separately — or kept |
Most solo optometrists should keep one corporation: a second entity adds accounting cost, rent and staff allocations, and pricing questions between related companies. Two corporations earn their keep when a non-optometrist genuinely co-owns the retail side, or when a lab or multi-location dispensary grows into its own business. Remember that TOSI still taxes dividends from a spouse-owned retail company at top rates unless the spouse actually works in it.
Three HST treatments under one roof
Optometry hits all three GST/HST categories at once, which is why the corporation's RT account should exist even though eye exams are exempt. Prescription eyeglasses and contact lenses are zero-rated — no tax charged, full input tax credits on frames, lenses, and lab costs — while non-prescription sunglasses, accessories, and drops are taxable. Because so much dispensary revenue is zero-rated, many practices recover more HST than they collect; miscoding those categories at the POS is the most expensive small error in this niche, and our optometry bookkeeping page shows how we map them.
Alongside RT, the corporation needs an RC account for its annual T2 and an RP payroll account for opticians, assistants, and any associates on salary.
Setup order, and the long game
Sequence the launch: incorporate under the OBCA, obtain the College's Certificate of Authorization, then bank account and CRA program accounts — and only then move billing and the dispensary into the corporation on a clean date. Keep the minute book current from day one; a tidy share ledger is what lets a future sale of qualifying shares use the $1.25 million lifetime capital gains exemption, and it is the first thing a buyer's accountant requests. Our incorporation and compliance service runs this sequence for you.
One more layer for many ODs: US optometry school debt, US income years, or equipment bought from US suppliers. Those threads change how we set up the corporation and its filings — start with our cross-border tax page for optometrists.

Common questions.
Can the dispensary sit inside my professional corporation?
Usually yes — dispensing prescription eyewear is ordinarily part of practising optometry, so most ODs run it inside the OPC. A separate retail corporation mainly makes sense when someone other than an optometrist needs to own a piece.
Can my spouse own shares of my OPC?
Generally no — optometry corporation shares must be held by licensed optometrists, unlike the family non-voting shares medicine and dentistry allow. A spouse could co-own a separate retail company, though TOSI limits the tax benefit.
Why register for HST when eye exams are exempt?
Because prescription eyewear is zero-rated: you charge no tax on it but recover input tax credits on frames, lenses, and lab fees. Without registration those credits are lost.
