SLP clinic payroll: CDAs, associates, and the school-year rhythm
The classification question in a speech-language pathology clinic splits cleanly along one line. Communicative Disorders Assistants are almost always employees, because CASLPO requires you to directly supervise their work. An associate SLP bringing her own caseload and clinical judgment has a real path to genuine contractor status instead. Add a hiring calendar tied to the school year, and payroll in this niche looks different from a typical small clinic.

CDAs are supervised, and supervision is control
A Communicative Disorders Assistant is not a regulated professional. CASLPO's own guidelines require an SLP to provide direct, on-site supervision of a CDA's work, from screening through implementing a therapy plan the SLP herself designed. That degree of direction is close to the textbook definition the CRA uses for an employment relationship. This is why CDAs working in a clinic are treated as employees with T4s, EI, CPP, and vacation pay — not contractors invoicing for their time. Clinics that have tried the contractor route with a CDA on the strength of a written agreement alone are the ones most likely to face a reassessment. The agreement does not change what CASLPO already requires the SLP to do. The same reasoning generally extends to any support personnel working under an SLP's direct clinical supervision, whatever their job title. Supervision defines the relationship, not the pay structure layered on top of it.
| Role | Who directs the work | Usual status |
|---|---|---|
| Communicative Disorders Assistant | Supervising SLP, by CASLPO requirement | Employee |
| Associate SLP with her own referrals and caseload | Herself, clinically and administratively | Genuine contractor is possible |
| Associate SLP filling clinic-assigned appointments on clinic equipment | The clinic's scheduling and referral pipeline | Looks like employment despite an invoice |
| Front desk and intake coordinator | Clinic owner | Employee |
An associate's contractor status depends on whose caseload it is
The clinics that hold up an associate's contractor status on review are the ones where the associate genuinely built or brought her own referral base. She also sets her own hours and fee within a reasonable range, and could see the same clients somewhere else if she chose to. A clinic that assigns appointments from its own intake list and sets the associate's schedule is describing an employee. This holds whatever the invoicing looks like, particularly if it also requires her to use clinic-branded materials. See how the CRA decides between employee and contractor before structuring a new associate arrangement, not after CRA asks about an existing one.
The school year sets the hiring and layoff calendar
A clinic running board contracts alongside private-pay work follows the school year's hiring calendar. It typically staffs up from September to June and scales back over the summer. This means employees hired against contract-funded hours may genuinely be laid off, not just quiet, when the contract pauses for the summer. That requires a proper Record of Employment at the layoff, not a gap in the pay runs that nobody documents. It also requires a clear rehire understanding for September if the same contract renews. Private-pay clinicians on the same payroll usually do not see the same seasonal dip. A blended staff therefore needs its ROE and scheduling logic handled role by role, not clinic-wide. Telepractice work has softened this pattern somewhat, since a contracted school visit that used to require in-person travel can sometimes continue remotely through a slower summer. The underlying funding still pauses with the school board's calendar, though, even when the delivery method does not.
Benefits do retention work a fee split alone cannot
Genuine SLP contractors are hard to retain purely on fee splits. A strong associate can take her caseload to another clinic or go fully independent. Clinics that want to keep experienced clinicians as employees often lean on a benefits package, paid CE time, and predictable scheduling instead of trying to out-bid the split. That is a compensation design question as much as a payroll one, and it belongs in the same conversation as the classification decision, not after it.
Part-time SLPs working several clinics still need a full T4 each
An employed SLP often splits her week across two or three clinics rather than working full-time. Each clinic that employs her as staff owes its own T4, its own CPP and EI remittances, and its own WSIB coverage for the hours worked there. There is no shared or netted arrangement between employers just because the total adds up to a full-time schedule. Clinics sometimes assume a part-time hire's other job means lighter obligations on their end. It does not — the remittance and vacation-pay math runs exactly the same as it would for a sole employer. We set each clinic's payroll up on that basis from the first pay run rather than adjusting it once a shared employee's other schedule comes to light.

Common questions.
Do we have to put our CDA on payroll?
In almost every case, yes. CASLPO requires direct on-site supervision of a CDA, which is the kind of control the CRA treats as an employment relationship regardless of what any contract says.
Can an associate SLP genuinely be a contractor?
Yes, if she brings her own caseload, sets her own schedule and fee, and could practise elsewhere. If the clinic assigns her appointments and clients from its own intake, the relationship looks like employment.
What happens to contract-funded staff over the summer?
If their hours are tied to a school board contract that pauses, a genuine layoff with a proper Record of Employment is usually correct. This is not an unpaid gap left undocumented on the payroll.
