Allergist and allergy testing in Mississauga

A referral-based clinic for children and adults, by appointment only.

Our Mississauga clinic is at 1550 South Gateway Rd, in the Dixie Road and Eglinton Avenue East area, close to Highways 401 and 403. It is one of three Dandelion Allergy Centre sites, and the team here sees children and adults who have been referred by their family doctor or another physician. Visits are by appointment only. There are no walk-ins, so the clinic books a time with you once your referral has arrived, and you can tell the team which location suits you when they call.

A first visit can take up to two hours, because your allergist reviews your history and symptoms before deciding which tests, if any, are needed. Every service on our services list is available at this clinic, including allergy skin testing, asthma care, spirometry, food challenges and immunotherapy. Care is covered by OHIP when you have a valid Ontario health card and a referral. Parking on site is complimentary, so there is no need to look for a spot on the street before you come in. Please bring your health card, referral details, a list of your medications and notes on your symptoms.
