The simple answer to this question is, “it depends”. One of Canada’s largest insurers, Intact Insurance, suggests that there is no requirement for scheduled checking of an unoccupied home. However in other cases, it can be as often as daily checks. In most cases a documented home check twice a week is sufficient to satisfy the insuring company’s requirements.
It is prudent to check with your insurance provider before you leave. What is important is that you be proactive in protecting your property while you’re away. Regardless of the insurance provisions, we live in Winnipeg, and if the furnace suddenly goes out in an unoccupied home in January you may arrive home facing a disaster.
