Today's Weather Trivia

23 November

1951: Thick fog with rain clouded western Quebec and the Eastern Townships, triggering several accidents. In vehicular accidents on the Laurentian Highway, the toll was 12 dead and 21 critically injured. Most victims died when a half-ton truck packed with carpenters and labourers skidded on ice in a shroud of fog, hurling its 17 occupants into a bed of rocks in a 10-m drop.
