What an OPC is, and what it is not
An Optometry Professional Corporation is an Ontario business corporation that holds a certificate of authorization from the College of Optometrists of Ontario and keeps it current. The name must include a shareholder's surname and the words "Professional Corporation", and every director and officer must themselves be a shareholder, which means an optometrist. One boundary matters most: incorporation does not shield clinical work. Professional liability stays personal and insured, while the corporation contains the business obligations: the lease, the equipment loans, the supplier accounts.
The shareholder rule that shapes the math
Ontario carved out an exception for physicians and dentists, whose family members may hold non-voting shares of their professional corporations. Optometrists did not get one. No spouse, no holding company, no family trust: only members of the College may own any share of an OPC. That closes the dividend-sprinkling conversation before TOSI even enters it, and it concentrates the incorporation case on two pillars — the deferral between Ontario's top personal rate of 53.53% and the 12.2% small-business rate, and the exit.
When the OPC pays for itself
The test is retention. If practice profit reliably exceeds what you draw to live on, the roughly forty-point deferral funds equipment, debt repayment and investing with dollars taxed once at 12.2%. If you spend everything the practice earns, incorporation mostly adds filings and fees. A dispensary-heavy build-out or a practice purchase pushes toward incorporating from day one, because loans repay far faster out of lightly taxed corporate dollars.
| Question | Sole proprietor | OPC |
|---|---|---|
| Tax on profit you keep invested | Up to 53.53% personally | About 12.2% on the first $500,000 |
| Malpractice exposure | Personal, insured | Still personal, insured — no change |
| Selling the practice | Asset sale only | Share sale possible, with the $1.25M exemption if the tests are met |
| Family shareholders | Not applicable | Not permitted — optometrists only |
| Admin each year | T1 with a T2125 | T2, minute book, College certificate to maintain |
The dispensary question
Because the dispensary is a genuine retail operation, owners sometimes ask whether it belongs in a separate, non-professional corporation that family members could own. The idea is not absurd, but dispensing prescription eyewear is regulated work in Ontario, and the College's rules limit how cleanly clinical and retail can be pulled apart. Sometimes a structure helps; often it adds cost and audit surface without the hoped-for benefit. We work it through case by case, and where an existing setup needs repair, Corporate Restructuring is its own engagement.
Moving an existing practice in
Optometrists who already run an unincorporated practice do not start over; they roll in. Equipment, inventory and goodwill can move into the new corporation on a tax-deferred basis under a section 85 rollover, with an elected transfer price that avoids triggering gains on the way in. The rollover paperwork is unglamorous and unforgiving, and it interacts with the practice's HST registration and the value of goodwill built up over years, so we treat it as part of the incorporation, not an afterthought billed separately. The first fiscal year-end is a choice too: a year-end placed after the winter benefits rush, rather than defaulting to December 31, spreads the compliance work into a quieter season.
Associate today, owner soon
New graduates usually associate first, and an associate with student debt and rent rarely clears the retention test; the honest advice is often to wait. The switch point tends to arrive with the first ownership conversation: buying into a practice, taking over a retiring optometrist's patient base, or signing a lease with a dispensary in the plan. Incorporating a few months ahead of that event keeps financing, College paperwork and CRA accounts from colliding in the same week the deal closes.
How we set one up
Our Incorporation engagement is quoted in writing after a free 15-minute discovery call. For an OPC that means articles drafted to the profession's share restrictions, the certificate of authorization application to the College, and CRA accounts opened in the right order: corporate tax, payroll, and HST registration from the start, because a dispensing practice is a registrant in practice from its first frame sale. You leave with a first-year compliance calendar and a pay-mix plan, not just a minute book. Most of the optometrists we incorporate practise in Mississauga and across the GTA, close enough to meet in person when the decisions are big.
