"I did a little google search and see that RBC is listed as one of CNSX,s dealers,so I have no concerns now"
RBC Dominion Securities is the listed dealer with the CNSX. I'm not sure, but I think that is different than RBC Direct Investing (who I deal through and is not listed as a dealer) It might be worth checking into further.
