• An event in 2018 in Niagara Falls, ON caused failure of several houses under construction. Nearby instrumentation measured wind gusts of up to 100 km/h; the National Building Code of Canada (NBCC) specifies a design (3-second gust) wind speed for the Niagara Falls region of 141 km/h. Several design features, particularly of modern houses, increase susceptibility to collapse during a particular stage in construction.
