Kejimkujik National Park is one of many National Parks in Canada. It is in the province of Nova Scotia. About 2 hour's drive southwest of Halifax, the capital of Nova Scotia, the park is well known for its great canoeing and hiking, and cross-country skiing in the winter.
Two cabins are available for use in the winter; Mason's, which has two bedrooms and a main room, and the Fire Tower, which has one room. Be warned, though -- the cabins may be icy cold in the winter when you first go in, but after about an hour and a half, you'll be sweltering in the heat.
Canoeing is also a popular passtime in the park. Keji is known as one of the prime places to canoe in Canada, with lots of campsites and well maintained portages throughout the park.
There is a brochure in the park that explains a lot of things about the park. The website to the park is here.
