This is, of course, due to the significant movement of the north magnetic pole in the last few years.  It is estimated that the poll is now moving about 55 km a year.  There are maps and some rather interesting explanations of the pole movement here and here

Most other Nunavut runways are not affected, as runways in Northern Domestic Airspace are designated in degrees True.
