Ummm... *Sounds like you should call an electrician out

Yeah, get an electrician to change not only the one problem
box, but also other boxes too that are perfectly fine, *instead
*of simply finding a dimmer that will fit. * I don't know where
some of you come up with your advice.

you do realize that a house built in the '60s likely has 2-3/4" (or
thereabouts) deep gem boxes and therefore wouldn't even meet current
NEC wire fill requirements unless used as a switch box on a switch
leg?

I realize that *I don't know what the national electric code in Canada
says about box size when simply replacing a switch with a
dimmer. *I do know that in my own house, if I found a dimmer
that fit, I'd use it instead of tearing out the old box and creating a
lot of potential work, eg wall repair, painting, etc.

the dimmer makes no difference. *2x 14/2 WG in a box with a device is
overfull according to current code with box sizes typical of those
used in the 60s. *AFAIK Canadian code is roughly equivalent to NEC.

Roughly equivalent doesn't mean you just apply the US NEC.
Bottom line is no one here knows the size of the box, how many
conductors are in it or the CA applicable code.



The fact that the dimmer doesn't physically fit just reinforces the
need to install a new box.

Who knows what size dimmer they had? RBM provided a link to
a potentially smaller one. I'd bet that if that one fits, almost
everyone faced with that situation would just use it instead of
installing a larger box. I would not force fit one in, but if he
can get it in with a reasonable fit, that's what I'd do.



I've had no problems replacing existing boxes in existing walls. *The
plastic old work boxes are physically larger than the metal ones, if
the hole in the wall is oversized.

And what happens if the cable that's stapled to studs now isn't
long enough to meet the minimum conductor length? Apply the NEC
and figure out how to extend the wire?
