Having an insurance background prior to the pizza business, I think you will seriously need to check your homeowners or tenants
personal insurance coverage. With most dwelling policies, there is an exclusion for business being conducted in the house and on the premesis. This would exclude coverage for the structure of the building and liability, in the event someone else were injured.
Most policies will allow for incidental business use, like using a business laptop at home, away from the primary pizza business.
If I recall, the policy will set a small limit of gross revenue to set the line of demarcation between defining incidental business and
full business use. The coverage definitions between US and Canada will be very similar.
I suggest inquiring with your insurance agent as to the coverage complications. The additional cost for insurance coverage could greatly reduce your profits. Not having the right insurance coverage, could financially ruin you.
