Alberta, Canada, is just about the only place in the world that is rat-free.
Norway rats are not native to North America but were introduced to the east coast around 1775, and gradually spread westward. Rats entered eastern Saskatchewan in the 1920s, and were first reported on the eastern border of Alberta in 1950 when an aggressive rat control program halted their advance. That rat-control program continues to maintain Alberta as an essentially rat-free province to date.

no rats---awesome...
brings up questions though:
shooting and trapping all good; poison though?
i wonder what their native mouse and ground animal populations are as a result? poisons don't differentiate... and does that mean Alberta has very few fox and bobcat populations? how about raptors? did these predators die or move away as an indirect or direct result of the poison?
i wonder if there has been any research on this...it could be valuable.
killing rats without poison could be a thing if it became profitable...natural dog and cat food anyone??
