Cleo needed constant care for a few months and the vets at St Lawrence were kind, compassionate, and they saved my girl. They have also treated one of my boys' urinary problems and I have always been very happy with all of the staff. Highly recommend!

Avoid this place at all cost! Zero compassion! Receptionist incredibly rude and hung up on me. My cat had not peed in almost 2 days and we had to rush him to Ottawa as Cornwall could not see him, understandably so as they were overbooked and understaffed. I spent 7 hours waiting in my car in Ottawa and they finally allowed him to go home but they forgot to put the special food in my bag. I contacted your office to pick up food as Ottawa said it would be no issue and I could not drive back and miss more work. You would not sell to me as my cat was not a patient. I was told by the vet in Ottawa that

Refused to sell/order specialized animal food required for my pets health/life. Gave me some excuse about extreme limited quantities (2 bags for whole clinic) offered by food production companies. Had to go to Quebec to get the pet food where puzzled vets confirmed no that such "rationing" exists.

This animal hospital did not advise me that they stopped after hour emergency care. I am a client and use this hospital for this reason. I had a major emergency and nowhere to go. Had they let me know I would have made a plan to ensure that my animals have somewhere else to go in case of emergency. I called other vets and they directed me to Alta vista in Ottawa who also no longer provide after hour emergency care. Irresponsible and unethical. I am taking my pets elsewhere. Hopefully they will be more transparent and honest.
