In addition to the usual tobogganing, you can book yourself a husky sled tour! The huskies are mostly rescue dogs and are super friendly. When we visited, there was just one which had a 'nervous' collar.
It's a gorgeous view sledding through the snow and meeting all the rescues. Our trip was a little stop and start as many of them seemed to be in a sniffing mood. Apparently there had been a female stray lurking around hence all the sniffing.
