Unlike the reefer issues I keep tabs on that trade on the OTC and are US based, a number of Canadian companies actually generally significant revenue.
I keep an Investors Hub streamer of reefer tickers, have since October 2016. It has grown to five webpages, 100 each page.
The Nasdaq's third tier, the AMEX can be just as bad, and last but not least, the OTC, it seems, are financial venues that reward failure.
