Winter in Canada threatens homes with burst pipes, water damage, energy inefficiency, and unsafe walkways. Key precautions include annual furnace tune-ups, filter maintenance, thermostat checks, and ensuring smoke and carbon monoxide detectors work. To prevent frozen pipes, disconnect hoses, insulate pipes, keep indoor temperatures steady, and know the main water shut-off. Sealing drafts and checking attic insulation can cut heating costs by 25%. Clear, salted walkways reduce accidents and damage. A warm, winter-ready home can attract buyers despite fewer listings.
