The top one is most likely a wolf skull as has been suggested.
Yes wolves come that close to town. We have had them here in Yellowknife in town and they have snatched peoples dogs. The last one I heard of was just a few blocks from my house.
We also get cougars,coyote, wolverines, lynx, black and grizzly bears coming into town and we are much more built up than Rankin is.
The bottom one is not a deer as Rankin is too far North of their range.
Most likely a caribou skull.
