Expert allergy care for every age, across the GTA.

Referral-based and OHIP-covered with a valid card. We see patients from across Ontario.
A full-service allergy clinic
We test for and manage the full range of allergic and immune conditions, tailored to each patient by referral. Hover any card for more.
Allergy skin testing
Skin prick testing for environmental allergens, foods, insect venom, and drugs.
A small drop of each allergen is placed on the skin and gently pricked. Results usually show within about 15 to 20 minutes, in a single visit.
Patch testing
For contact dermatitis from fragrances, metals, and preservatives.
Patches are worn on the back for about 48 hours, then read over follow-up visits to find what your skin is reacting to.
Oral food challenges
Controlled ingestion of a suspected allergen under medical supervision.
Done in clinic with the care team present, to confirm whether a food is truly a problem or can be reintroduced safely.
Chronic hives (urticaria)
Investigating and managing unexplained or recurring hives and swelling.
We look for triggers and patterns, then build a plan to reduce flare-ups and keep you more comfortable.
Anaphylaxis management
Epinephrine auto-injector guidance and personalized action plans.
We help you recognize early signs, carry and use your auto-injector confidently, and plan ahead for emergencies.
Asthma management
Spirometry, inhaler education, and biologic therapy where appropriate.
We assess your breathing, refine inhaler technique, and consider advanced options for harder to control asthma.
Know what is in the air, and when
Triggers shift through the year here. General timing below; your own pattern may differ, and an allergist can help you pin it down.
