Over a year ago, a friend of many years from Bathurst Inlet, NU taught me how to build a traditional sled known as a Qamutiq (or Komatik or Komatic). It was great knowledge to learn and I did retain a lot that day, I still would forget something so I did a quick search.
I found these plans how to build a qamutiq online. It appears that a couple organizations, including the Government of Nunavut and the Qikiqtani Inuit Association, put these plans together for others to use.
If you are interested in building your own you can download the plans here (PDF).
