When I was working for a vet in Vernon, it was common practice to just dump any bodies at the landfill that hadn't been paid for to be cremated. Owners were given the option of private cremation, where they get the ashes back, communal cremation, where the body is burned with others, or, if the owner didn't want to pay for any disposal, and didn't want to bury the body themselves, the bodies were taken to the dump.
All the vets in Vernon did this, and it was perfectly legal, so I'm sure the Vernon SPCA bodies went to the dump too. Vernon takes animals to a vet to be killed, so they are put in a freezer at the vets rather than a dumpster.
But they end up at the dump, little bodies, betrayed in life and treated like garbage in death.
I have trouble believing this is legal, but apparently it is in Vernon. Seems the North Okanagan Regional District isn't concerned about the level of Euthanyl in the bodies - seems they don't care if barbiturates are passed through the food chain and environment by gulls and other scavengers like eagles, coyotes and bears.
