How to become a speech-language pathologist in Ontario

To practise as a speech-language pathologist in Ontario you need a professional master’s degree in speech-language pathology, a pass on the Canadian Entry to Practice (CETP) Exam, and registration with the College of Audiologists and Speech-Language Pathologists of Ontario (CASLPO). Most new graduates start on an initial certificate, complete a six-month mentorship, and then move to a general certificate. From the first day of university, the whole route usually takes six to seven years.

This guide walks through each step, with the rules as CASLPO publishes them. Requirements change, so confirm the details on the CASLPO and university pages linked in the sources before you apply.

Step 1: A bachelor’s degree with the right prerequisites

Every Ontario program requires a four-year undergraduate degree, but none requires a specific major. Students arrive from linguistics, psychology, health sciences, kinesiology, education and many other fields. What matters is the prerequisite courses, which differ by program.

The University of Toronto, for example, asks for a mid-B average in the final year and a B+ in each prerequisite course, plus at least 14 hours of experience in a setting supervised by a speech-language pathologist. Laurentian asks for a 75% average and credits in statistics or research methods, anatomy or physiology, psychology (including developmental psychology) and linguistics (including phonetics or phonology). Western lists prerequisite courses and volunteer experience as requirements for its MClSc.

Two practical notes. First, the prerequisites overlap heavily across programs, so a second-year student who takes developmental psychology, phonetics, anatomy, statistics and a linguistics survey course will be close to eligible everywhere. Second, programs count volunteer and paid hours differently, so track dates, settings and the supervising clinician’s name from the start.

Step 2: An accredited master’s program

CASLPO’s standard pathway is for graduates of programs accredited by the Council for Accreditation of Canadian University Programs in Audiology and Speech-Language Pathology (CACUP-ASLP). As of the council’s current listing, five Ontario programs are accredited.

Applications to all five go through the Ontario Rehabilitation Sciences Programs Application Service (ORPAS), with a deadline in early January for entry the following September. Programs are small and competitive; the University of Toronto, for example, planned to admit about 60 students for 2025 to 2026. Accreditation terms expire and are renewed, and programs occasionally gain or lose status, so check the CACUP-ASLP list for the current cycle. Graduates of a Canadian program with “candidate” status follow the international route described below.

Clinical hours

Every accredited program builds supervised placements into the degree. CASLPO’s academic framework requires a minimum of 350 direct-contact clinical practicum hours, with at least 300 in the major area (speech-language pathology) and 20 in the minor area (audiology). Programs typically exceed this. Placements span pediatric and adult settings, which is worth knowing if you already have a preference, because most students do not choose their own sites.

Step 3: The CETP exam and CASLPO registration

The exam

Since April 1, 2021, passing the CETP exam has been a non-exemptible requirement for CASLPO registration. The exam is competency-based and multiple choice, built on the national competency profile for the profession, and is administered by Speech-Language & Audiology Canada (SAC) on behalf of the provincial regulators. There are two exam windows per year, in spring and fall, with enrollment deadlines a few months ahead.

Key rules from CASLPO’s exam page:

• Applicants have a maximum of three attempts.
• Recent graduates of accredited Canadian programs (within 12 months of the exam) can enroll before applying to CASLPO; the program director confirms eligibility with SAC directly.
• Anyone who has failed once, or who graduated more than 12 months before the exam, must apply to CASLPO and be deemed eligible before enrolling.
• The old SAC Clinical Certification Exam and the American Praxis exam are not accepted in place of the CETP.

Passing the exam does not itself allow you to practise. Registration with CASLPO does.

Applying to CASLPO

Applications are online. For graduates of accredited Canadian programs the non-exemptible requirements set out in Ontario Regulation 21/12 are the professional master’s degree, eligibility to work in Canada, and the CETP exam. CASLPO offers four certificate classes: initial, general, academic and non-practising. New graduates almost always start with an initial certificate.

Initial certificate

The initial certificate is for applicants who have not yet completed 750 hours of patient care in another jurisdiction within the last three years. Two features make it different from a general certificate:

1. You need an offer of employment in Ontario and a mentor in place before CASLPO will issue it. The mentorship and the job must start on the same day.
2. You may be registered before writing the CETP exam for the first time, as long as you attempt it within six months. If you fail that first attempt, you must stop practising within 30 business days and the initial certificate expires until you pass.

The certificate is valid for at least six months and can be extended, but the regulation sets a hard limit of 24 months from the date of issue.

Mentorship

Mentorship is a condition of every initial certificate. Over a minimum of six months the mentee must provide at least 500 hours of patient care and receive at least 48 hours of guidance from a mentor who holds a general certificate and meets CASLPO’s criteria. The mentor must directly observe the mentee’s practice and submit a midterm and final evaluation through the Mentorship Self-Assessment Tool. CASLPO is explicit that mentorship is not supervision: the mentee is accountable for their own clinical decisions from day one.

General certificate

Once the final mentorship report is accepted and the exam is passed, CASLPO changes the registration to a general certificate, a process the College says takes four to six weeks. Applicants who already hold a general-equivalent certificate in another Canadian province, or who have 750 hours of practice elsewhere and have passed the exam, can apply directly for a general certificate without mentorship.

Title protection: what you cannot do before registration

Section 8 of the Audiology and Speech-Language Pathology Act, 1991 restricts the titles “speech-language pathologist”, “speech therapist” and “audiologist”, including any variation, abbreviation or equivalent in another language. It also prohibits anyone who is not a registrant from holding themselves out as qualified to practise. Section 10 sets fines of up to $25,000 for a first offence and $50,000 for a subsequent one.

For students and graduates this means:

• You cannot sign as “SLP”, “S-LP”, “MHSc SLP” or “speech therapist” until your name appears on the CASLPO Public Register. “MHSc candidate” or “speech-language pathology graduate” is acceptable.
• An employer may hire you before registration only as support personnel, and CASLPO’s employer FAQ says you may not use the titles or hold yourself out as qualified in that role.
• Social media, business cards, websites and directory listings all count. CASLPO’s Use of Restricted Titles standard applies to applicants and students as well as registrants.

The guide to checking whether a speech-language pathologist is registered shows what the public sees on the register, which is a useful check on your own listing once it appears.

Internationally educated applicants

Graduates of programs outside Canada, including the United States, and of non-accredited Canadian programs, apply through a separate pathway. The application can only begin after the professional master’s degree is complete. CASLPO assesses the degree against its Academic Equivalency Framework; the degree must include coursework, a research component and clinical practicum, with the same 350-hour minimum. Where the only gap is in the minor area (audiology), a panel of the Registration Committee can issue an initial certificate with a condition to complete those hours during mentorship.

CASLPO recommends that international applicants submit a complete application at least 16 to 20 weeks before the exam date they are aiming for, because eligibility to write the CETP must be confirmed before enrollment. SAC membership and the S-LP(C) designation are not part of this process, and holding American ASHA certification does not replace the CETP in Ontario.

What the job looks like in Ontario

Speech-language pathologists in Ontario work across four main sectors, and most clinicians move between them over a career.

• Preschool Speech and Language Program agencies. Publicly funded lead agencies, hospitals and children’s treatment centres deliver the PSL program for children from birth to school entry. The work is heavily parent-coaching based, with assessment, group programs and some direct therapy.
• School boards. Board speech-language pathologists assess language and literacy, consult with teachers and contribute to Individual Education Plans. Direct one-to-one therapy is limited in many boards. Articulation, fluency and voice in schools are usually handled by School-Based Rehabilitation Services through children’s treatment centres.
• Hospitals and rehabilitation. Acute care, rehabilitation and complex continuing care roles cover swallowing, aphasia, voice and cognitive-communication, mostly with adults.
• Private practice. Private clinicians see children and adults whose families pay directly, through extended health benefits or through Ontario Autism Program funding. CASLPO’s Advertising Standards and record-keeping rules apply, and the clinician carries the business risk.

Job postings in all sectors list CASLPO registration as a requirement, and bilingual French and English clinicians are in demand across the province.

SAC membership and certification

Speech-Language & Audiology Canada is the national professional association, not a regulator. Membership is voluntary. Students in a Canadian or international graduate program can join free as student associates, and graduating students are eligible for up to a year of free professional liability insurance through SAC’s partner. Full members can enroll in the SAC Certification Program, which requires 15 continuing education equivalents a year and allows the S-LP(C) designation. SAC states plainly that certification does not grant the right to practise.

What happens next

A typical timeline for a student starting an Ontario master’s program in September looks like this: graduate in June or August of the second year, write the fall CETP sitting, secure a job offer and a mentor, apply for an initial certificate, complete the six-month mentorship, and move to a general certificate roughly a year after graduation.
