What to Expect

How to prepare

  • We strive to provide comprehensive, family-centered, multi-disciplinary team care to our patients. Thus, the initial appointment is typically longer than follow-up appointments. Please prepare to be here for 1-2 hours (on average), especially if your child is booked for pre-visit pulmonary function testing
  • Allergy skin-prick testing is often completed during the appointment. To avoid affecting the results, we ask that you have your child avoid antihistamines (e.g., Benadryl, Reactine, Claritin, Aerius, etc.) FOUR days prior to the appointment. Allergy Skin-prick Testing involves introducing a small amount of the substance, or allergen onto the surface of the skin in the form of a “poke”. We utilize small devices called “Duotips” which are NOT needles. Skin-prick testing may be uncomfortable for your child. Please feel free to bring tools of distraction or items your child might find comforting.
  • If your child was referred to us for an “Oral Food Challenge”, please note that your child’s first visit is a consultation ONLY, and will not involve feeding. We often require repeat allergy testing to confirm the diagnosis before arranging for an Oral Food Challenge

What to bring

  • Your child’s Health Card. The Ministry of Health and Long Term Care requires us to validate your health card at every clinic visit 
  • Any relevant test results (x-rays) or letters from your child’s doctor or pediatrician. 
  • Any notes or questions that you may have 
  • List of current allergies 
  • Medications, including aerochambers and puffers

When you arrive, please check-in at the reception desk. The Business Clerk will register you in the electronic system so that your team will know that you have arrived.

Note: If your child is ill with any antibiotic resistant organism, MRSA, a communicable disease (such as Chicken Pox), or a respiratory infection, please notify reception staff prior to your scheduled appointment. Our clinic number is (905) 521-2100 x 73861/75253

Oral Food Challenges

Oral Food Challenge (OFC) involves the slow and cautious introduction of food into the child’s diet. If your child has a food allergy and is a current patient of ours, an OFC may be suggested to confirm the presence of an allergy. You and your child would have instructions and recommendations provided to you by your physician. Please review the following documents prior to your child’s OFC appointment. Please contact your physician if you have any questions.
