Dr. Lee is an amazing professional and human being, who goes above and beyond any reasonable expectation for the care of his patients. He has been managing my immunodeficiency for several years, coordinating with my hematologist at St. Michael's (to whom he referred me to) and very patiently addressed my concerns and made referrals as needed. He started me on sub-cutaneous IgG a few years ago, and that has helped reduce my previous recurrent infections.

Dr. Lee is an excellent specialist. He is very knowledgeable, straightforward, efficient and answers all your questions without rushing. He put me on the right track to correct an immune problem and I am so grateful for his care and guidance.

I cannot sing enough praise for Dr. Lee! I have been going to him for a few years now. At first it was for allergies than I started talking to him about my eczema. He was able to put me on drugs my dermatologist could not I've been essentially eczema free for 7 months now as a result. This has been such a game changer for me. Not only that but the same drugs help with my allergies...so instead of multiple drugs I'm on one that helps with all my allergy/eczema symptoms and have now avoided going on less effective drugs that have more severe side effects. Huge Kudos for Dr. Lee!!!

Dr. Lee is effective, kind and is on the cutting edge of his specialty. He tells it like it is so if you don't want honesty then he may not be the doctor for you. His staff are a cut above - always responsive and helpful. I LOVE being able to communicate with this office via email! Thanks to Dr. Lee and staff!!

Was referred to him for his supposed world class knowledge on a rare condition I have. I knew more about my disease then he did. He was utterly useless, not attentive, very dismissive and RUDE!

I recently saw dr lee through zoom and phone. I found him an exceptional listener and very matter of fact in his diagnosis. Like others he found out something’s others could not and explained it to me through a shared power point. I did exactly as he suggested of stopping my decency on Advil and voila my hives and swelling gone.

I’ve been a patient of doctor lee for nearly 10 years and the comment below feels like a personal insult. Dr Lee tries his best and he’s replaced most of his terrible staff. He sees a lot of patients in any given day and I’m not sure how he’s expected to remember everyone. You won’t find another forward thinking and cutting edge allergist or asthma specialist in Canada or the world.

I don't care what anyone says, Dr. Lee is the best ever.

Had an appointment booked, when I showed up there was a sign on the door saying that the office was closed that day with no explanation as to why. I received no phone call from his staff telling me the office would be closed, and had booked time off of work to go to this appointment. Very disappointed in the lack of professionalism from his staff. He is a good allergist, who I had a pleasant appointment with before, but this experience was ridiculous.

I love Dr Jason Lee! It's therapeutic just talking to him sometimes even when nothing can be done. His talk and voice alone is relaxing. He should be teaching other doctors on bed side manners. Like others have said before, you almost feel an instant chemistry and connection to Dr Lee. I don't think this is a gimmick or trick, he is just a nice soul. I saw him for what I thought was a very complicated problem and daily allergic reactions. Even though I did not even take the treatment he recommended, just knowing what I had put me instantly at ease and my hives calmed down. He also found I'm taking too much ibuprofen which may have been the cause. I'm hive free now and a lot less anxious. To think I flew in to see him after having seen three other world famous allergists. It was a personal friend who recommended Dr Lee and word of mouth is still best it seems
