“This report hopes to provide more accurate data and analysis on secondary units to housing stakeholders, particularly at the municipal level,” said Anthony Passarelli, Senior Analyst with CMHC. “Along with the creation of new custom-built rental apartment constructions, secondary units are helping to address the shortage of affordable rental housing.”

Once secondary suites were identified, it could be analyzed whether certain location- and property-specific attributes affected the likelihood of a home having a secondary unit.

Report highlights:

  • Almost one in six basic housing in Toronto had a secondary unit (15.4%), the highest ratio in Ontarioa total of an estimated 75,000 secondary units.
  • The estimated percentage of basic housing containing a secondary unit in Brampton was 9.6%, the second highest ratio among municipalities in this survey.
  • The estimated percentage of basic housing containing a secondary unit in Mississauga was also above average at 7.4%.
  • The estimated percentages of basic housing with secondary units were much lower Ottawa (3.3%) and Hamilton (3.1%).
  • The two more northern Ontario cities of Thunder Bay (8.4%) and Greater Sudbury (8.9%) had a higher incidence of secondary suites compared to most other cities in this report.
  • Basement apartments were the most common type of secondary unit.
  • Municipalities with a low supply of custom-built, owner-occupied flats and subsidized rental housing, such as Brampton, Ajax and Barrie, tended to have a higher ratio of properties to a secondary entity.
  • Municipalities with persistently low positions, such as Toronto, Mississauga, Guelph and Kingston were more likely to have secondary devices.
  • Due to their smaller floor space and design features, one-story homes were more likely to have a secondary unit than other styles.
  • Secondary units are more prevalent in the older established neighborhoods that are highly sought after by tenants due to their proximity to their downtown cores and great amenities.
  • Municipalities with a large percentage of newer homes, especially those built in the last decade, had a low probability of having a secondary unit.

Data mapping:

Along with this analysis, this report also provides the concentration of secondary suites through a series of data cards. Data mapping is available for the cities in Toronto, Hamilton, Ottawa, Mississauga, and Brampton.
