RE:RE:Withholding tax
As I understand it now, there are some big tax issues unless you hold it in a TFSA or RRSP.
The difference between the SIB price and $3 (PUC) will count as a dividend for tax purposes. That's offset somewhat by a capital loss between your purchase price and $3.
Since dividends are taxed at a higher rate than dividends, there's no arb available unless your earnings are very low and you have capital gains to offset.
