Neighbourhoods with "physical" or explicit gating with security checkpoints and patrols are extremely rare, being absent in some of Canada's richest neighbourhoods such as Bridle Path, Toronto. This is generally attributed to the lower crime rate in Canadian cities. Furthermore, municipal planning laws in many Canadian provinces ban locked gates on public roads as a public health issue since they deny emergency vehicles quick access.
A noted exception in Canada is Arbutus Ridge, an age-restricted community constructed between 1988 and 1992 on the southeastern coast of Vancouver Island.
Do not all municipalities have bylaws requiring there to be no gates blocking emergency vehicles? How did Arbutus Ridge get the exception? It's surprising as it's in a government city.
