Best Emergency Vet Clinic ever! Unfortunately, we have been in twice… Both times we were helped quickly. The staff and doctors were all thorough and professional and treated our puppy with care.
It’s never fun when your fur baby is sick. But knowing that VCA is out there 24/7 Has Been very comforting
We were confident in the doctors, their diagnosis and their treatment. 10 out of 10 I would highly recommend this clinic.

I believe they are understaffed, which leads to very long waiting times, often exceeding 4 to 5 hours. Avoid if possible!

Had to lay one kitty to rest the other night and Ontario VCA was very welcoming and helpful in the process. It was a heavy loss for my wife and I. Thank You Ontario VCA for Your kindness and patience with us.

I brought my cat’s newborn kitten to this place, and what I witnessed there was unacceptable. The kitten was extremely small and fragile, but I personally watched the staff feed him in a way that, in my opinion, was too fast and unsafe. I believe this contributed to his rapid decline in less than 5 hours. He went was vigorous and eating to dead. I went to see him this morning because Braner was insisting that I Euthanize him immediately. I am in healthcare. I could clearly hear fluid in his chest before he passed, and I believe aspiration is what caused his decline. This was due to staff incompetence.
Dr. Braner was the veterinarian on last night. She is not knowledgeable, dismissive, avoided answering basic questions, and showed very little compassion throughout the experience. I did not feel heard, respected, or supported. I deeply regret trusting this clinic and leaving my kitten there longer. I wish I had taken her home when she started to improve.
I spent thousands of dollars, and in my view, the care was negligent, incompetent and unprofessional. I will never bring any of my animals here again, and I believe they should refund what I paid. This experience broke my trust in this place completely.
My cat is grieving her kitten. She continues to walk around and is leaving her other kittens in the nest searching for the one VCA harmed and vocalizing. It is heartbreaking to watch this. They need to think about how their actions impact animals and their owners.
