I just did a google search for “Oxbow Edmonton, Alberta, Canada” and got this opinion on a guinea pig site:
Sherwood Park, Edmonton, Alberta area
Practice limited to Small Animal and Exotic Pets
Dr. Louis Kwantes, BSc, DVM, MSc Park Veterinary Centre 101 Broadway Blvd Sherwood Park, AB T8H 2A8
Phone: (780)-417-1119 Fax: (780)-417-2600
Dr. Kwantes and the other vets at Park Veterinary Centre seem very competent, knowledgeable and caring….the clinic is clean and bright, the reception staff and the vet techs are friendly and gentle. The clinic also sells Oxbow small animal products.
If you know where that is, or if it’s not far, I’d suggest calling them to see what they carry for rabbits. If you said you’d buy it from them, you could probably get them to add your requests to their next order.
I always got my Oxbow products from a vet I didn’t otherwise use, and later from my own vet who started carrying it. Never saw it anywhere else.
