2009 - Hurricane Juan, 29 September
Perhaps the most damaging storm in Halifax's history, Hurricane Juan severely damaged the cathedral. In one powerful gust the hurricane ripped off the transept roof. About two- and one-half tons of wood frame, roofing material and copper flashing landed in a nearby parking lot. With the roof gone, wind and rain entered the cathedral, causing major damage to the structure and contents. The damage also meant that the diocese's electoral synod, scheduled for 22 November had to be moved from the cathedral to St. James Church, Armdale, in Halifax.
