SLP incorporation: your professional corporation, and the clinic around it

A CASLPO health profession corporation is profession-specific

The Regulated Health Professions Act allows both audiologists and speech-language pathologists to incorporate, and CASLPO issues the certificate of authorization that makes it official — but a single health profession corporation can only have shareholders, directors, and officers who are registrants of the same profession. An SLP and an audiologist practising side by side in the same clinic cannot simply share one professional corporation between them; each needs her own, holding her own clinical billings, even if the clinic itself operates as a single visible brand to clients. The corporation's name has to reflect that too — CASLPO requires the practitioner's own name in the corporate name along with wording identifying it as a professional corporation, so a generic clinic brand name on its own will not satisfy the certificate application. The clinic can still market itself under a shared trade name to clients — that is a marketing decision, separate from what CASLPO requires the underlying corporation to be called.

The clinic and the professional corporation are different things

A multidisciplinary clinic — SLPs, audiologists, and often CDAs or admin staff under one lease — is usually run through an ordinary operating corporation that owns the lease, employs the support staff, and holds the equipment, separate from any individual practitioner's health profession corporation. Each incorporated clinician then bills her own HPC for the clinical work she personally performs, while the operating corporation invoices for facility fees, equipment use, or admin support if that is how the group has structured its economics. Clinics that skip this separation and run everyone's billing through one entity without sorting out whose corporation actually earned what tend to find the structure difficult to unwind later, especially if an audiologist or SLP eventually leaves. Getting the split right at the outset also makes each practitioner's own year-end filing far simpler, since her T2 only needs to reconcile against her own clinical billings rather than against a shared pool that has to be untangled retroactively.

What incorporating changes for a solo practitioner

For an SLP practising largely alone, the case for incorporating is the standard one: active income retained inside the corporation is taxed at the small business rate rather than your personal marginal rate, which builds room for a cash reserve against a slow referral season or an eventual parental or sick leave, before that money is drawn out and taxed again as salary or dividends. See what a professional corporation is and who can have one for the mechanics that apply across regulated professions generally. It is a retention and timing tool, not a discount on tax owed on money you actually spend personally. It also carries a real ongoing cost — incorporation and certificate application fees up front, then an annual corporate return, minute-book maintenance, and typically higher accounting fees than filing a personal T2125 — so the reserve you plan to build needs to be large enough to justify that cost before it makes sense to switch.

Watch personal services business status if you work through one contract

An incorporated SLP whose entire practice runs through a single clinic or a single long-term board contract, on that clinic's schedule and using its intake pipeline, risks being assessed as a personal services business rather than an active business — which removes the small business deduction and most of the ordinary expense claims the corporation would otherwise get. An SLP who bills several different sources — her own private-pay caseload, more than one board contract, occasional insurer work — has a much stronger case that the corporation is running an active practice rather than standing in for a single employer.

The practical fix, where the risk is real, is usually diversification rather than abandoning incorporation outright: adding a second contract, taking on some private-pay referrals, or picking up telepractice work through a different source all strengthen the case that the corporation controls its own client relationships. We flag this before incorporation, not after a review has already started asking the question. Neither college nor CRA publishes a bright-line rule on how many sources are enough, which is exactly why this is a judgment call worth making with someone who has looked at the underlying test rather than guessing at a number.
