​​Seven Year Coverage

Your home’s seven year warranty covers major structural defects (MSD) and begins on the date you take possession of the home and ends on the day before the seventh anniversary of that date.  For example, if your home’s date of possession is October 23, 2005, the seven year MSD warranty begins on October 23, 2005 and remains in effect until and including October 22, 2012.

A major structural defect is defined in the The Ontario New Home Warranties Plan Act  as:

In respect of a post June 30, 2012 home, any defect in work or materials in respect of a building, including a crack, distortion or displacement of a structural load-bearing element of the building, if it,

(i) results in failure of a structural load-bearing element of the building,

(ii) materially and adversely affects the ability of a structural load-bearing element of the building to carry, bear and resist applicable structural loads for the usual and ordinary service life of the element, or

(iii) materially and adversely affects the use of a significant portion of the building for usual and ordinary purposes of a residential dwelling and having regard to any specific use provisions set out in the purchase agreement for the home

The seven year MSD warranty includes significant damage due to soil movement*, major cracks in basement walls, collapse or serious distortion of joints or roof structure and chemical failure of materials.  In addition to the general exclusions, the seven year MSD warranty specifically excludes: dampness not arising from failure of a load-bearing portion of the building; damage to drains or services; and damage to finishes.

*Soil movement means subsidence, expansion or lateral movement of the soil not caused by flood, earthquake, "acts of God" or any other cause beyond the reasonable control of the builder.
