Not in MA. I asked an electrician who I work
with about that awhile back because I frequently
run into that situation. His answer was that
extenders are only needed if the wall material
is combustible. (Generally that would mean wood.)

It may be different in Canada. You use a different

On steel studs you could make a case.
