Every picture on this site is an editorial-style illustration generated for it; none shows a real customer, a specific home or any listed provider, and the infrared views are illustrative, not measurements. The data drawings and the facts on each page come from the public sources listed here. If a credit is wrong or missing, write to dave@clickshift.ca and it will be fixed.

Data drawn into the pages

  • Housing portraits on city pages are drawn from the Statistics Canada 2021 Census of Population (dwelling type, period of construction, tenure and heating fuel), under the Statistics Canada Open Licence.
  • Climate figures (heating degree-days, design temperatures) come from Environment and Climate Change Canada normals and the NRCan HOT2000 weather library; climate profiles cite their sources on each page.
  • Program and rebate facts are checked against the official program pages (Natural Resources Canada, provincial governments and utilities), with the verification date shown beside each one.
  • Test guides and the glossary draw on Health Canada, NRCan, the National Building Code, CSA, the EPA, ENERGY STAR and the other sources listed under each entry.
