Toronto police have launched an investigation after notes with anti-Semitic messages were left on doors at a condominium in the city, residents say.

Photos shared with the Star show a small note bearing the phrase “no Jews” above a swastika written in red ink. Mezuzahs were vandalized or stolen, residents confirmed.

Helen Chaiton, who has lived in the building for 18 years, said her rabbi had visited Sunday afternoon to replace her mezuzah that was “completely vandalized.” Hours later, in the evening, her new mezuzah had been stolen with an “obscene message” left at her front door.

“At the foot of my door was an expletive, and a swastika,” she said. “I am staying strong. I come from a family of Holocaust survivors.”

“Anti-Semitism has no place in Toronto. Our Jewish residents should not have to face hatred on their doorsteps,” Mayor John Tory said in a statement on Monday.

“These acts, and the people who carry them out, do not represent Toronto or Torontonians,” the mayor continued.

Police confirmed that the Hate Crime Unit was investigating several other incidents over the past few weeks that were “motivated by hate.”
