A 5 dollar coin makes sense to me; however, the elimination of the penny does not.
From a current economic standpoint, it does unfortunately make sense. It costs around $6 to make a penny now, and there are around 600 pennies for every person in Canada. You do the math.
$1:
Why eliminate the penny is prices will still have a 1 cent denomination? Why eliminate all one cent denominations, leading to 2 cent denominations for pricing. We could then just artificially double the value of the dollar, so that two past dollars would by one future dollar, and two past pennies would buy 1 future penny? thus the need for a penny again.

I think getting rid of the penny is going to cause some seriously bad pricing issues, because any way you shake it, somebody ends up losing money where they wouldn't have previously.
