After being a patient of this practice for over 25 years, I was affected by the optometrists' job action, as I am a senior. (Although I am in favour of the government ensuring pay equity for Canadian optometrists, I believe the job action was an unprofessional choice which only impacted patients and had no impact on government.).

Covid also had prevented me from seeking an appointment prior to vaccines coming available. Because of these delays, I was overdue for an eye exam and my glasses were becoming scratched and coatings flaking off. I could not even get a replacement pair because

Warning parents, this is not a good place to bring young children for eye exams. I brought my five year old kid to see Dr. Shen, who looked like a nice lady but with very limited experience and patience handling young children. Dr. Shen kept blaming my child for non-cooperative behaviour which made her unable to do her job. She even said, child above 3 should be able to cooperate. Well, my child is a normal kid, who goes to a normal school with no behaviour concerns from teachers. Clearly, Dr. Shen could not handle young children and used a 5 year old's non-cooperation as an excuse for her incompetence

I've been going to Dr. Harrison here for years! All the staff are professional and treat you with respect. When I come, I don't wait long and get-in-get-out. I go every year because of a complicated eye disorder I have, and I wouldn't want any one else working on my eyes.
