I'll be happier if the PPS climbs to $6 before the year is out, which would mean I could only add 1,000 shares.  Only being able to add 500 would be even better :-)  I love the TFSA, its the best thing Harper did during his time in office in my opinion.  $63,500 is the cumulative max as of Jan 1, 2019, or $127,000 per taxpaying couple provided they've been taxpayers since 2009.  

Instead of shares though I'll likely go with warrants :-)

As for short interest, I checked Wednesday, yesterday and today and the number hadn't been updated through to November 30th yet.
