JMHO - I would think that as long as they are authentic ZCC shares that they should be okay in a registered account. If holders received AGM packages and were allowed to vote, that should be proof that they are authentic ZCC shares and registered with Computershare. The shares most of us hold had been thought to not trade anywhere and yet were allowed in registered accounts. What we were always told was they had to trade on a recognized (I forget the actual word used) exchange which left OTC out. We had our brokerages tell us (I did anyway) that we had to move them out to a non-registered account. We didn't accept that and it wasn't true. We got ZCC involved and they proved that ZCC is a public company ergo the shares were allowed to be in registered accounts and our brokerages then accepted it. If one really feels uneasy about the authenticity of their shares, order certificates. I believe though, that as long as one receives the official information that involves Computershare, they should be authentic and be allowed. You might not receive info. directly from Computershare as you are only a beneficial shareholder but your brokerage is the registered shareholder and does receive this to pass on to you. JMHO
