AbstractBuilding damage caused by a moderately strong tornado in the Pilon subdivision of Aylmer, Quebec on Thursday, August 4, 1994 is described. Atmospheric Environment Services classified this tornado as "Force 3" (on a scale of 0 to 5) with winds as high as 270 kmlh. The most severe structural damage observed, however, seems to indicate peak speeds in the 150 to 200 km/h range. There were no deaths and few serious injuries, but insurance claims for housing repair alone were expected to reach $10 million. To reduce future tornado losses, recommendations are made for improving quality control of criticalconnections.
