Read the guide →Why it matters
Temperatures across Canadian provinces regularly drop below −20°C. Water in uninsulated pipes freezes in hours. Early preparation avoids emergency repairs mid-winter.
Provincial codes (Ontario Building Code, Alberta Building Code) specify minimum insulation values and installation standards. These guides reference the relevant sections.
Annual furnace inspections, bi-annual roof checks, and seasonal weatherstripping reviews follow manufacturer timelines and align with most home insurance requirements.
