The Manitoba Electoral Boundaries Commission had proposed combining Flin Flon and The Pas constituencies due to population numbers.  After holding hearings in the north they changed that plan.  Their report states;

To best ensure effective representation, the Commission significantly reduced the size of Keewatinook, the largest electoral division in the province. It also addressed the previous significant population imbalance that existed

between Flin Flon and The Pas. The Commission adjusted the boundaries so that each northern electoral division has no more than 10 to 14 community areas situated therein.

The Commission has also made other changes. Given that The Pas electoral division will now encompass a large part of Lake Winnipeg, the name was changed to The Pas–Kameesak because Kameesak in Cree means “big”, a likely reference to Lake Winnipeg. Finally, in response to input during the public hearings, the Thompson electoral division was adjusted to include the communities of Nelson House, Gillam, Churchill and the other communities along the railroad line.

They add under the new boundaries, the four electoral divisions in the north have better balanced populations, are more similar in size and respect travel patterns as well as communities of interest.
