If you reach -40 C/F regularly you are in zone 2!
If you are not grafting the apples yourself or mail ordering them from the
handful of nurseries that specialize in trees for the northernmost zones you
are not doing it right. There is generally no way of knowing what the
rootstock you have is otherwise.
Claude's assessment of the available hardy rootstocks is about right. I do,
however, think that apples on Antonovka seedlings will work well for you if
you get them from someplace like St. Lawrence or Fedco. Anything they have
that would cross with the Antonovka to produce rootstocks is likely to be
very hardy, too. Del Stubbs and Jim Fruth, both of whom frequent the list
have orchards near Bemidji and Pequot Lakes respectively can tell you what's
done well for them. In northern MN it's unlikely that you'd hit your lowest
temperatures without some snow. Edmonton has those lovely Chinooks (so I've
heard, anyway) which can cause midwinter snowmelts.
