Thrift shops in the rest of Canada

We've been entertaining the idea of a trip to Québec and returning by RV (to carry the loot) - an idea that is now coming into fruition.

To that end, I have been researching and cataloging thrift shops in the rest of the country.  One starts with the usual suspects such as the Salvation Army, MCC, Bibles for Missions and Habitat for Humanity. There is also of course the Society of St Vincent de Paul.

I've found a few organisations that operate in one part of the country but not others.  Here are a few interesting ones.

Goodwill Industries - part of the U.S. umbrella organisation - has many chapters in Ontario, and a few in Alberta and Manitoba.

The wife of a Governor-General formed  charity called May Court and quite a few chapters exist, not least in Ottawa.  The focus seems to be on high-end women's clothing and it would appear many operated non-profit consignment shops originally but many have changed to thrift shops.

I would have expected there would be more IODE thrift shops but there's only one in Ontario so B.C. has 3x s many.

Québec is more challenging as one has to find terms for non-profit and charity shops without getting all sorts of commercial listings.  There seem to be a small number operating under the umbrella of The United Way.

If you need to ask, the database for Ontario is almost as big as the rest of the country.
