It's in Canada. And it is Vancouver Island not Victoria.
If there is a Victoria island, I have never heard of it. We do have a Vancouver island, on which the city of Victoria is located, and you can bring your dog if you like.
The area of Victoria Island - Canada - is 217,291 square kilometers.

victoria island :) m.s.
Depends which one you mean. Three out of five of them are. Victoria Island, Nigeria definitely is. Ditto Victoria Island, Chile and Victoria Island in California. Google Earth shows Victoria Island in the Russian Arctic is well within (i.e. north of) the Arctic Circle. That leaves Victoria Island, Canada, which I'm guessing is the one that prompted the question. No, it is not south of the Arctic Circle. In fact, Victoria Island, Canada is entirely within (i.e. north of) the Arctic Circle, the largest island in the world with this distinction (and ninth largest island in the world, period).
Victoria is the largest city in Vancouver Island.
