Members of the public attending council meetings and other public events at Vancouver City Hall will now go through an enhanced security screening process.
The city says in a statement that the change is responding to the evolving security environment and following in the footsteps of other Canadian cities that have adopted similar security measures.
However, the city released no further details on the nature of the potential security concerns.
It says city hall is remaining open and accessible to everyone and the new measures are aimed at creating a safe place.
