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 pets 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.
