In this publication, the measure of housing utilisation is based on the criteria of the Canadian National Occupancy Standard (CNOS), which determines the number of bedrooms required to adequately accommodate a dwelling's occupants.

In 2017–18:
  • There was an average of 2.6 persons per household and 3.2 bedrooms per dwelling.
  • Almost one in twenty (4%) of households were in need of at least one more bedroom.
  • More than three quarters (79%) of households had at least one bedroom spare.

Over the last twenty years:
    • The mean number of persons per household gradually declined from 2.7 in 1997–98 to 2.5 in 2005–06, then slowly increased to 2.6 in 2017–18.
    • The number of bedrooms per dwelling has increased from 3.0 in 1997–98 to 3.2 in 2017–18.
