not trying to start a debate here, but i do not think that is accurate.
e.g.
https://www.statista.com/statistics/1243350...ada-by-revenue/ shows that is not even in top ten. and i should know, i work for one of them
what may not make it so obvious is that many times the big retailers have a lot of brands under their umbrella so one would not realize that they are pretty much everywhere.
sorry for hijacking the thread, back to dollar store products now
ps: i realized that if you click the link you end up on a page hidden behind a paywall. if that is so jsut search google for "top 10 retail stores in canada dollar amount" and this article will be first (at least it is for me)
