Do I need a building permit for my renovation in Sarnia?

What should a contractor's written contract include?
A solid contract should specify the scope of work in detail, materials and brands to be used, start and end dates, payment schedule tied to milestones, warranty on workmanship, and a process for handling changes or overruns. Never pay more than 10–15% upfront.
