Ottawa Veterinary Hospital

In business since 1954
We’re a compassionate, full-service veterinary hospital serving the dogs & cats of the Ottawa and Marsellies area.  We plan to serve our customers and their pets with expert care and higher quality goods in a professional and friendly atmosphere.

The Ottawa Veterinary Hospital was built and founded by Dr. James Wellington Harry Neil in 1954. We want to remember him here.

Dr. Neil was born July 24, 1926, in Lucan, Ontario. He served in the Canadian Army from 1945 to 1946. He graduated from the University of Toronto Veterinary School in 1951 and worked as a veterinarian in Ottawa from 1951 to 1953. He practiced in St. Thomas from 1953 to 1954 and returned to Ottawa and built and operated the Ottawa Veterinary Hospital from which he retired in 1998. He was a lifetime member of the American, Illinois and Chicago Veterinarians’ Associations as well as the Northern Illinois Veterinary Medicine Association. He also belonged to the International and Fox Valley Safari Clubs, Christ Episcopal Church of Ottawa, and the Omega Tau Sigma veterinary fraternity the Masons, Shriners , and the the Elks Lodge 588 in Ottawa, staying very active in the community until his death. Dr. Neil passed away on Jan. 11, 2009, at the age of 82.

The business was sold to Dr. Patricia Hoagland in 1998.
