Golf - the article you posted is correct as it relates to deliberate over contributions made during the year made for the sole purpose of sheltering gains from tax by simply paying the 1% penalty.  So, if (God willing) RVX were to go up next week and you sold shares or warrants in your TFSA then this 100% advantage tax would apply because you did it in the same year in which you had or still had an over contribution.

However, if you don’t sell anything prior to December 31 and your over contribution is completely covered by the new contribution room that will be available on January 1 to absorb that excess then I think you are ok.  You’ll simply pay the penalty for, say, November and December and that will be the end of it.  Any ‘red flag’ will have disappeared and life goes on as normal.  You may chose to not sell anything in 2020 or later and I really can’t see this following anyone around indefinitely, especially if it’s a ‘one-off’.  It’s probably not a good idea to make a habit of this by for example doing the same thing again in March 2020 for the 2021 contribution, etc.  The CRA tends to notice patterns.  But a one timer for 6 weeks, I doubt it’s an issue because by the time you are notified you’ll already have the excess covered.

Before I get a barrage of posts please know that I’m not advocating anyone do this.  It’s just my take on a hypothetical situation.
