All the shares I own are in tfsa and rrsp too, but the warrants...  Is there anyone here who might know if there is a way to exercise warrants in a tfsa/rrsp??

If that is not possible, I could consider exercising warrants in cash accounts now and swapping them over to the tfsa at today's price.  If I believe sp will increase in coming months that may be the incentive to exercise now.  Any suggestions or strategies others are thinking about in regard to their warrants?
