Hi Koo,
All the shares I had received from the Zenith spinoff have moved into my TFSA with no issue. If I can recall (that long ago), RVX provided a letter to all us shareholders that satisified CRA and in my case Scotiabank.
I hope that helps!
PS - I have been quite for several years now (frustrated... but quiet). Thanks to all for your great insight and opinions.
Long
