For Medical Professional Corporations
Insurance built for the way a medical practice actually earns, saves, and transfers.
An Ontario MPC is a small business with an unusual income curve, an outsized disability-risk profile, and a deferred-tax problem most generalist advisors never solve. This is what to do about it.
Why this page exists
I came into financial services from inside the healthcare system — originally trained as a physiotherapist in India, and later working in Canada as an EMG technologist alongside physicians, surgeons, and specialists. I know how a practice actually runs, how clinical income flows, and where the real risks sit.
That background changes the advice. The structures below are not a generic ‘doctor package’ — they are the same institutional COLI, buy-sell, and disability work used by Ontario CCPCs, adapted for the MPC framework and the clinical realities of medical practice.
For Ontario Medical Professional Corporations
Protecting the lifetime value of your clinical practice.
We bridge the gap between procedural medicine and advanced corporate tax law. Specialized insurance architecture for Ontario Medical Professional Corporations.
Anatomy of an optimized MPC
Three structural layers. One coordinated flow of capital.
Click each layer to inspect how clinical income, corporate insurance, and estate liquidity are sequenced inside the MPC.
Active practice income
OHIP and private procedural billings flow directly into your MPC. Unoptimized, retained earnings sitting in taxable portfolios are subjected to passive tax rates exceeding 50% and trigger the Adjusted Aggregate Investment Income (AAII) grind, eroding your Small Business Deduction (SBD).
Serving specialists and their accounting partners across the London, Ontario medical community and the broader provincial hospital network.
The four problems we solve
Most MPCs are structured for billing, not for tax-efficient wealth transfer.
Trapped corporate capital
Retained earnings inside an MPC are taxed at the small-business rate going in — but pulling them out as salary or dividend triggers tax again at personal rates approaching 53.53%. Without a plan, much of the practice's lifetime savings is taxed twice.
The AAII grind on the SBD
GIC and dividend income inside the MPC counts as Aggregate Investment Income. Every dollar above C$50K reduces the C$500K Small Business Deduction limit by five — quietly pushing active practice income into the 26.5% general rate.
Clinical-grade disability risk
A surgeon, dentist, or interventionalist who loses fine motor function may still be able to teach or consult — but cannot perform the procedures the practice is built on. Standard ‘any-occupation’ definitions will not pay. True own-occupation, specialty-specific coverage is non-negotiable.
Succession and estate liquidity
On death, MPC shares are deemed disposed at fair market value. Because Ontario regulations limit MPC share ownership strictly to licensed members of the same profession, non-physician family members cannot hold voting shares. The estate faces a strict, legally mandated timeline to restructure or liquidate — and pre-funded, tax-free liquidity through the CDA is what makes that transition orderly instead of forced.
Regulatory compliance — RHPA & CPSO
Strict college rules. Structured architecture, not workaround layering.
Because the Regulated Health Professions Act (RHPA) and CPSO bylaws strictly prevent traditional holding-company layering, your corporate surplus often sits trapped inside the MPC. We structure tax-exempt life insurance architectures directly onto your MPC balance sheet, ensuring strict compliance with your professional college while shielding your retained earnings from passive tax drag.
How we structure it
Four moving parts. Coordinated so they do not work against each other.
COLI inside the MPC
Permanent life insurance owned, paid for, and beneficiary'd by the corporation. Premiums funded with corporate dollars taxed at 12.20% rather than personal dollars taxed at ~53%. Cash value grows on a tax-sheltered basis and is excluded from AAII — so the SBD is preserved while the corporate balance sheet quietly compounds.
Capital Dividend Account on death
Death benefit minus the policy's Adjusted Cost Basis credits the CDA under s. 89(1). The MPC files Form T2054 and Schedule 89, then pays a tax-free capital dividend to the estate. For a late-life policy where ACB has decayed toward zero, this can move the entire death benefit out of the corporation without personal tax.
Own-occupation disability for clinicians
Specialty-specific definitions that pay if you cannot perform the substantial duties of your medical specialty — even if you can still work in another role. Layered with Business Overhead Expense coverage so the practice's rent, staff, and lease payments are funded while you recover.
Compliant Holdco & family security structures
Where the MPC's professional-college rules and corporate structure permit a connected holding company, the policy can be positioned so intercorporate dividends flow under s. 112 in accordance with CPSO/RHPA bylaws — isolating the asset from any future malpractice or trade-creditor exposure on the operating practice. Compliance with professional-college share-ownership rules is the first step in every structure, not an afterthought; family-trust layering is reviewed on a case-by-case basis against those same bylaws.
The funding arbitrage
A premium paid by the MPC costs roughly half of one paid personally.
C$25,000 premium funded personally (top Ontario bracket)
~C$53,800 of pre-tax personal income required
Same C$25,000 premium funded inside the MPC (12.2% combined Ontario SBD rate)
~C$28,474 of pre-tax corporate income required
Annual cash-flow advantage of corporate funding
~C$25,300 — a 47% reduction in the cost of the same coverage
Illustrative only. Actual numbers depend on the physician's marginal rate, the MPC's active-business income bracket, and whether the policy is structured to credit the CDA at death. Every plan is modeled to the specific practice before any recommendation.

Pre-tax income required across premium range
Step-by-step breakdown — MPC funding at 12.20%
- 1. Target after-tax premium the carrier needs to receive: $25,000
- 2. Effective corporate tax retained on active income: 12.20% → after-tax fraction = 1 − 0.1220 = 0.8780
- 3. Pre-tax corporate income required = $25,000 ÷ 0.8780 = $28,473.80
- 4. Corporate tax paid on that income = $3,473.80
- 5. Implied after-tax premium remitted to the insurer = $28,473.80 − $3,473.80 = $25,000.00
- 6. Personally funded equivalent at 53.53% marginal = $25,000 ÷ 0.4647 = $53,798.15 (personal tax of $28,798.15)
- 7. Cash-flow advantage of corporate funding = $25,324.35 per year (47.07%)

Assumptions & limitations
What “personal marginal rate” covers
The combined federal + Ontario personal income tax rate applied to the next dollar of T4 salary or non-eligible dividend you would draw from the MPC to pay the premium personally. Default 53.53% is Ontario's top combined bracket (2024+, income over ~$246K). It does not include CPP, EHT, or the marginal cost of crossing OAS clawback thresholds.
What the 12.2% SBD rate assumes
Federal 9% + Ontario 3.2% on active business income under the $500K small business limit. Assumes the MPC has not had its SBD ground down by Aggregate Investment Income (AAII) above $50K, and is not part of an associated group sharing the limit. Income above the SBD threshold is taxed at the ~26.5% general corporate rate.
Key exclusions
- No s. 15(1) shareholder-benefit assessment if policy beneficiary is misaligned with payer
- No modeling of CDA credit at death (death benefit − ACB)
- No premium tax (Ontario 2% on life insurance) layered on the corporate premium
- Ignores RDTOH on passive investment income inside the MPC
- Ignores time-value of money and policy ACB grind
When this model breaks
- MPC is associated with other CCPCs sharing the $500K SBD
- AAII has fully ground out the SBD — use ~26.5% general rate
- Premiums funded from a Holdco via s. 112 dividends (add tier)
- Policy is personally beneficial — CRA may reassess as a taxable benefit
- U.S.-person physician (PFIC / 7702 exposure on Canadian permanent insurance)

Who this is for
Physicians, surgeons, and specialists incorporated through CPSO and operating an MPC with retained earnings building inside the corporation.
Dentists, oral surgeons, and orthodontists operating through a dental professional corporation, with overhead-heavy practices and own-occupation disability needs.
Group practices and medical partnerships needing a coordinated buy-sell, key-clinician coverage, and a shared CDA strategy across multiple distinct MPCs that share a central cost-centre or clinic overhead.
