I have some merchandise that I would like to market to Dollar Stores,
Dollar Plus Stores in Ontario, Canada. Could somebody guide me to a
mailing list of such stores?

Hi, 

This is a Pipe delimited file which you can import into just about any
program. The Pipe is this symbol  |  or Shift-\ .. you'll see it.

There are Dollar and Discount stores in this list. Some of the
discount stores you probably won't want, but you can filter those out
using the Category field. I'll leave that to you because you might
want them.

You can download the file here:
