I sent a letter to my new councillor and got a reply back, not a canned one:
Thank your email. We completely understand your concerns. Since Canada now recognizes Palestine as a state, they were able to apply to have their flag raised at city hall and it was approved by city administration without input from council.
Flag raising at city hall is divisive and a distraction. Councillor Tyers supports the motion to stop all national flags, aside from the Canadian flag, from flying at city hall. This will allow us to put this incident behind us so we can focus on municipal issues.
