Alta Vista: the hospital district and the medical professional corporation

Alta Vista is where a lot of Ottawa’s medicine lives outside the hospital walls. The Ottawa Hospital’s General campus sits on Smyth Road, the Riverside campus is minutes south, and the streets between them hold the homes of a large share of the physicians, specialists, and senior clinicians who work there. The tax question that comes up again and again in this neighbourhood is the same one: should I incorporate. A medical professional corporation is genuinely useful, but it is misunderstood in both directions, and the wrong expectation is expensive.

What incorporation actually buys a physician

The first thing to be clear about is that incorporating does not lower the tax on money a doctor needs to live on. Income that comes out of the corporation to fund the household is taxed in the physician’s hands at ordinary personal rates, incorporated or not. The province lets physicians incorporate as professionals, but the corporation does not change what your own spending costs in tax.

What it changes is the treatment of money you do not need this year. A Canadian- controlled private corporation pays a low combined federal and Ontario rate on its first half-million of active business income under the small business deduction, far below the top personal rate. So a specialist at the General who bills well over what the household spends can leave the surplus in the corporation, pay the low corporate rate now, and invest or defer the personal tax until the money is actually drawn. That deferral is the real engine. It is worth a great deal to a high-billing physician with room to save, and close to nothing to a resident or early-career doctor who spends everything they earn. Incorporation is a tool for retaining earnings, not a discount on drawing them.

Salary, dividends, and the mix that is not automatic

Once a corporation exists, the physician has to decide how to pay themselves, and there is no single right answer. Salary is deductible to the corporation, creates RRSP contribution room, and requires CPP contributions from both the corporation and the individual. Dividends are paid from after-tax corporate income, carry no CPP, and build no RRSP room, but can be simpler and are sometimes the better choice depending on the year.

The mix matters more than people expect, and it interacts with things that have nothing to do with the office. A physician’s family with young children may lean toward enough salary to maximise RRSP room and childcare-related planning; one near retirement may weight it differently to manage the pension and the eventual wind-down of the corporation. There is also the tax on passive investment income earned inside the corporation, which above a threshold begins to claw back access to that valuable small business rate. A Riverside clinician who lets a large investment portfolio accumulate inside the corporation without watching that threshold can quietly lose the very advantage the corporation was set up to give. The remuneration decision is a yearly one, made against that year’s income, spending, and savings, not a setting you choose once.

The costs and the paperwork are real

A medical professional corporation is not free to run. It files its own T2 corporate return every year, keeps its own books, may need to register for and file GST/HST depending on the services, and must comply with the college’s rules on professional corporations including who may hold shares. There are accounting fees, and there is a discipline required: the corporation’s money is the corporation’s, and treating the business account as a personal chequing account is exactly the kind of thing that undoes the structure.

For a physician clearing well above household needs, those costs are small against the deferral and the flexibility. For one who is not yet at that point, they can outweigh the benefit, which is why the honest answer to “should I incorporate” in Alta Vista is sometimes “not yet.” The break-even depends on how much you can leave in the corporation and for how long, and that is a calculation, not a rule of thumb.

Getting the timing right near the hospital

The pattern I see across the streets around the Ottawa Hospital campuses is physicians incorporating either too early, before there is retained income to shelter, or too late, after years of paying full personal tax on money they could have deferred. Both are avoidable with a look at the actual numbers: billings, household spending, existing RRSP and TFSA room, and the savings the corporation would realistically hold.

That is a conversation worth having before the incorporation, not after, because the setup, the share structure, and the first year’s remuneration mix are easier to do right than to unwind. If you are a physician or specialist in Alta Vista weighing a professional corporation, or already have one and are not sure the salary-dividend mix still fits, Khaled Hawari can run the break-even on your real figures and set the structure up to do what you actually need it to do.
