Why are you scared of everything?

This CDIC insurance is in effect as close as one can get to a Government of Canada guarantee that anyone with a GIC investment (principal and accumulated interest) totalling up to $100,000 will have every cent of that money returned to them if the company in question offers investors CDIC insurance. Whether that is one of the major Canadian banks or someonelike HCG or EQB, that guarantee is absolutely identical. 
You can make up stories, conspiracy theories, create opinions or whatever from wherever your mind wanders off to but none of these irrational guesses matter. If the CDIC coverage is in place, the investor's money is absolutely at no risk of loss up to that total of $100,000 regardless of the name of the financial institution from which you purchased your GIC. It is that simple and all of these weird theories that are presented to say otherwise are clearly wrong. Time to get over it. 

Game, set, match.
