As for Marshall, well, he knew a thing or two about getting out of town in a hurry.
When a river near his home flooded three years ago, an evacuation order was issued, and he boarded a truck to safety - but begrudgingly, to say the least.
"He's not exactly very cooperative to load up into the truck," Coutu told Metro News. "The last time it took us three RCMP officers, myself, and he's over 100 pounds - not much for car rides."
This time there would be no evacuation for Marshall.
But it turns out, he does a pretty good job of looking after himself.
On Monday, officers from Canada's Royal Canadian Mounted Police (RCMP) were going door to door in the city, looking for those who may have been left behind.
They came across some horses.
