The LaSalle Heights disaster occurred in the early morning of March 1, 1965 in the city of LaSalle, Quebec when a gas line explosion destroyed a number of low-cost housing units.
 In all, 28 people lost their lives, 39 were injured and 200 left homeless.
 Most of the casualties were women and children because many men had left for work.
 The casualties might have been higher had it not been the start of the month when many men left earlier than usual to pay their monthly rent at the rental office.

An Aso Oke Hat (pronounced ), a type of soft fez, is a traditional Yoruba hat that is made of hand woven Aso Oke, cotton, velvet, or damask.
 In the Yoruba language, this hat is called a fila.
 Although these hats originated in Nigeria they are worn by many men of African descent.
 Typically, the top of the hat slouches to one side, and rests above the wearer's ear.
 It is commonly worn with the Yoruba formal attire, Agbada (equally made with Aso Oke, lace or cotton) or brocade dashiki suits.
 Many men wear a bowler hat with the lace dashiki suit.
 However, an aso oke hat or crown style kufi cap are the most common choices when wearing any other type of formal attire.
