Ketamine Therapy in Mississauga

Ketamine-assisted therapy is available in Mississauga through Port Credit Therapy Centre, ATMA CENA's GTA member clinic at 12 Front Street South. Mississauga sits at the heart of Ontario's most concentrated ketamine therapy market — alongside Braxia Health Mississauga and Ontario Ketamine and Infusion Centre — and serves as ATMA CENA's primary western GTA access point for patients in Mississauga, Etobicoke, Brampton, Oakville, and west Toronto. This guide covers what's available locally, who qualifies, what it costs, and how to access care.

Key takeaways

• Mississauga's ATMA CENA member clinic is Port Credit Therapy Centre at 12 Front Street South — a 4-minute walk from Port Credit GO station.
• Mississauga is ATMA CENA's primary GTA access point: corporate clinics are in Alberta only; member clinics serve the Toronto area through Port Credit Therapy Centre, Vaughan, Oakville, and Hamilton.
• CPSO Out-of-Hospital Premises Inspection Program (OHPIP) governs IV/IM ketamine clinics; CPSO standards require deep-sedation-equivalent care.
• OHIP covers physician consultations but not the ketamine drug or administration; WSIB Ontario covers ketamine on multiple specialty formularies for compensable injuries.

What is ketamine-assisted therapy?

Ketamine therapy uses sub-anaesthetic doses of ketamine — a Health Canada-approved anaesthetic — to treat conditions including treatment-resistant depression, PTSD, anxiety, OCD, and chronic pain. Health Canada has approved ketamine as an anaesthetic; psychiatric use is off-label, a legal and common practice in Canadian medicine. Spravato (intranasal esketamine) is Health Canada-approved for treatment-resistant MDD as of May 2020.

When ketamine is paired with structured psychotherapy before, during, and after dosing, the treatment is called ketamine-assisted psychotherapy (KAP) or ketamine-assisted therapy (KAT). Port Credit Therapy Centre uses this model. For the full mechanism breakdown, see What Is Ketamine Therapy?.

Patients in Mississauga or the western GTA can book a free information call to discuss eligibility and the care pathway.

How ketamine works

Ketamine acts on the brain's glutamate system through NMDA (N-methyl-D-aspartate) receptor antagonism, triggering a downstream surge of glutamate, AMPA receptor activation, and BDNF (brain-derived neurotrophic factor) release that stimulates synaptogenesis — the formation of new neural connections within 24 to 72 hours of a dose (Lullau et al., 2023). Conventional antidepressants take 4 to 6 weeks to act; ketamine can produce antidepressant effects within 2 to 72 hours of a single IV dose. The Canadian Network for Mood and Anxiety Treatments (CANMAT) places IV racemic ketamine as a third-line treatment for adults with treatment-resistant depression (TRD) (Swainson et al., 2021).

Port Credit Therapy Centre — ATMA CENA's Mississauga member clinic

Port Credit Therapy Centre is in the Port Credit waterfront village in southern Mississauga — walkable from Port Credit GO station (4-minute walk) on the Lakeshore West line. The clinical model uses ATMA CENA's three-phase KAP structure — preparation, dosing, integration — with somatic trauma yoga and group integration as adjunctive offerings. The clinic serves Mississauga locals and patients across the western GTA who find Port Credit closer or more accessible than downtown Toronto.

Mississauga as ATMA CENA's primary GTA access point

ATMA CENA does not operate a corporate clinic in Toronto. The GTA member clinic network — Mississauga, Vaughan, Oakville, and Hamilton — provides ATMA CENA's GTA-area ketamine access. Port Credit Therapy Centre is the largest of the western GTA member clinics and the closest to downtown Toronto via the QEW (~30 minutes) or GO Transit Lakeshore West (~25 minutes from Union Station).

For the broader GTA picture including downtown Toronto's other clinics and the network architecture, see Ketamine Therapy in Toronto and the GTA.

Ontario regulatory framework

Two regulatory layers govern Mississauga ketamine clinics.

Federal — Health Canada. Ketamine is a Schedule I controlled substance, prescribed off-label for psychiatric use. Spravato is Health Canada-approved for treatment-resistant MDD as of May 2020.

Provincial — CPSO. The College of Physicians and Surgeons of Ontario (CPSO) does not have a specific ketamine policy, but IV/IM ketamine administration falls under the Out-of-Hospital Premises Inspection Program (OHPIP). Clinics must be CPSO-accredited out-of-hospital premises (OHPs). CPSO standards: "Patients receiving [ketamine] must receive care consistent with deep sedation even if moderate sedation is intended."

The practical effect for Mississauga patients: facility-level oversight and physician sedation credentialing are robust; clinics that are not CPSO-OHP accredited cannot legally provide IV/IM ketamine in Ontario.

OHIP, ODB, and Ontario insurance

OHIP: Covers physician consultations but not the ketamine drug or administration for psychiatric indications.

Ontario Drug Benefit (ODB) / Exceptional Access Program (EAP): Spravato is not on the standard ODB formulary. Prescribers can submit Exceptional Access requests via the SADIE portal — case-by-case approval. Generic racemic ketamine for psychiatric use has no ODB or EAP pathway.

WSIB Ontario: Covers ketamine and Spravato on multiple specialty formularies (musculoskeletal, CNS/PNS, psychotraumatic, chronic pain, serious injury) with prior authorization for compensable injuries.

Private insurance: Spravato is the form most likely to be covered with prior authorization for documented TRD. Generic IV/IM ketamine for psychiatric use is generally not covered. Note: Alberta Blue Cross's psychedelic-assisted therapy coverage does not extend to Ontario residents.

Mississauga's ketamine landscape

Mississauga has the highest concentration of ketamine providers in the GTA outside downtown Toronto:

• Port Credit Therapy Centre (ATMA CENA member clinic; KAP model; 12 Front St S)
• Braxia Health Mississauga (1100 Dundas St W) — Canada's first dedicated ketamine clinic for mood disorders, established 2018; multi-modal (IV, sublingual, Spravato)
• Ontario Ketamine and Infusion Centre (1000 Middlegate Rd) — IV-focused; physician-academic team; Level II OHP-accredited
• Pain Care Clinics (5225 Satellite Dr) — clinic-dosing + virtual therapy hybrid

ATMA CENA's differentiation in Mississauga: the KAP model (preparation, dosing, integration psychotherapy bundled), multidisciplinary team, somatic and group integration adjuncts. Most competitors offer infusion-only models without bundled psychotherapy.

Local Mississauga practical notes

• Population: ~720k (Canada's 6th largest city; largest Toronto suburb)
