Banned in Quebec until at least 1960 - what was it?

   Adrien Dulude, 36, was fined $200 upon his arrival in Montreal by train in Windsor station from Toronto on Nov. 6, 1959 for possessing 12 units of a substance that you probably didn't know was banned in Quebec until at least 1960.
  Anybody want to guess?


  Yes! We have an answer!
   Vodka was banned in Quebec until 1960 at least, as this article from the era explains, leading Dulude to being fined for his 12 bottles.
   Premier Duplessis banned it during the Cold War, as punishment for being popular in Russia.

Al Palmer confirms the ban in Aug. 1960

   Duplessis also justified the ban by saying that vodka sales cut into Quebec-made whiskey blanc.
   Vodka was not banned in other provinces or states, as far as we know.
   The article I linked to only mentions that authorities were considering allowing its re-entry onto the Quebec booze market but did not specifically confirm whether actual Russian-made vodka would be permitted or whether domestically-produced versions thereof would be so privileged.
  We don't know when the ban began but it was still on in November  1960 and ended on Dec. 28, 1960.
