how does the tax advantage of a tfsa compare to a regular investment account 
take two savers joe and jane at the beginning of the year joe puts c 6 000 in an investment account earning 7 per year jane contributes the same amount but to a tfsa earning 7 they will each have c 6 420 after a year but jane can withdraw all c 6 420 and owe no taxes on it whereas joe would be taxed on the earnings of c 420
