If CRJ/CLGRF trades a million shares - is a million shares not a million shares, or what? Not everything is a massive conspiracy. It does not really matter if you buy CLGRF and the shares come from a Canadian exchange. If you read about MM's it is a normal thing to do this, and yes, theoretically it could be used in some nefarious scheme but again, specifically to what end? I can't see this being an effective tool of manipulation at all.
Here is a former MM explaining some of the real ways and tricks they use to manipulate stocks:
Claude is Canadian and most of its pricing power is on the Canadian side, CRJ. CLGRF, one best performing stocks, is not being manipulated downward unless you have some compelling proof aside from what you have offered.
Personally I think seeing boogie men everywhere is a tad naive but that's just me.
