Now is the time to complete the Canadian penny collection. It has a beginning and an end, so just getting one of each year shouldn't be too hard.
Yes, I see it ceasing, just like adoption of the metric system... I think the dollar bill will cease first, replaced by the dollar coin. The penny will be eliminated as the dollar begins to lose more and more value. I would say 10 years from now sounds about right to me. I'm ready now for the penny to go now though.
