Ownership follows professional rules.
The profession and the province decide who can hold shares in a professional corporation. Each buy-in, retirement, or family arrangement changes the cap table, and the dates matter.
Ownership and share classesHealthcare and professional groups
Dental, medical, veterinary, and pharmacy groups often run on professional corporations, a clinic company, a management company, and a property company. TaxDesk shows how they connect, keeps each company’s tax records separate, and remembers who owned what, and when.

Why it gets complicated
Practices are structured this way for good reasons. The result is several companies with different tax profiles that have to stay consistent.
The profession and the province decide who can hold shares in a professional corporation. Each buy-in, retirement, or family arrangement changes the cap table, and the dates matter.
Ownership and share classesThe practice, the management company, and the property company often hold different CRA accounts. Registrations and filing settings can differ across the group, and each belongs on its own record.
