All the way from Montreal, on her way to Alberta but got left behind in Toronto. Sounds like some country heartbreak song. And I'm sure Cora's heart is broken, being left behind in a strange city while her owner moves on without her but she puts on a brave face waiting for someone to take her home.
The best way to check on the adoption status of this dog (and other dogs and cats and other small domestic animals) is to visit Toronto Animal Services adoption website or call 416 338 6668 for the Toronto Animal Services South shelter. If the dog is no longer on the TAS adoption website, it's probably because it's been adopted already.
