When you buy a new home, you want to know that your investment is safe. For many home buyers, one of the deciding factors in purchasing a new home is the warranty that comes with it. The home building industry is a strong advocate of consumer protection, and new home warranty is an essential aspect of builders' commitment to quality and consumer satisfaction. Warranty coverage varies across the country, but is manditory in Ontario. Coverage provided by the registered builder is supported by The Tarion Warranty Corporation.
