True perhaps in the areas you are thinking of Olin, but very NOT true in
other areas.

VG happens to be in one of the "mechas" for electronics stores: Toronto.

For downtown Toronto try Supremetronic for "regular" electronics stuff
(they are near Spadina and College, there's also a second store that
carries similar stuff on the south side of College just east of
Spadina). You can also hit Active Surplus on Queen, but don't go there
for something specific.

For uptown there are more options on Gordon Baker near Victoria Park and
Steeles. Active Electronics and Sayal are both there.

Sayal is the best without question, they have a few other locations as
well:

There are more stores in the west end, but I'm not familiar with that
area so I can't point the OP to any in particular.

Very rarely do I have to place orders at Digikey since my work is very
close to Sayal and Active.
