How many cabinet making shops are there in the US and Canada? At a
minimum I'm looking for the total number of Cabinet Makers in the US
but I would like a list of all cabinet makers in the US and Canada, if
possible.

Hi 2day,
According to the Reference USA database, there are 17,854 Cabinet
Makers in the US.

Reference USA, a searchable database of 12 million US businesses, is
one of the best resources for information on American businesses.
Using a customized search, you can research by SIC codes, geographic
region, business size and other criteria. Reference USA is a
subscription (fee-based) database that is offered by most public and
academic libraries free of charge . Contact your local library or
local librarian for help getting access to Reference USA and learning
how to use its interface.

Searching by the SIC code of Cabinet Makers (175103) in all of the US
brings back 17,854 resulting hits. The list provides contact
information, estimated sales, company size, year that it was added to
the database and other information.
searching by SIC code Cabinets (571236) brings back 6,778 hits.
searching by SIC code Cabinet Makers Equipment and Supplies (503120)
brings back 168 hits.

My advice, go to your local library and use reference USA.
I don't have any good suggestions for Canadian business information.
Hope this helps,
