well it actually is a service if you google it..and there are businesses in Toronto. If you read the reviews on this one you can see that having it mobile would have actually been a good idea.

another one states..they will pick the animal up and then do the creamation at their farm
We provide pet cremation services to the direct public. You can call us direct for assistance or you can ask for our service at your pet’s clinic. We have the cremation unit fitted onto our truck, but because of local regulations, we are unable to extend the services at your residential location. Therefore cremation will be carried out at our farm.

Without a doubt there is room in the pet industry for pet funeral homes. It is a very tough time for pet owners and having a patient kind soul to walk them through the process is comforting, as it is with the loss of a human family member. I have dealt with many grieving pet owners and they can require very different approaches. I know very few owners would appreciate an onsite crematory at the clinic, no, not in this day and age. I will admit there are a few who do not trust that they get back the ashes of their pet and only their pet and they may want to attend a cremation but most pet owner, no. I used to work at a vet clinic that had a crematory out back many years ago and no it is not appreciated. All MOO
