I wonder how this will affect sales taxation, as the tax rate isn't a multiple of 5 in all provinces, and hence the amount of tax collected on a purchase will have to be either be rounded down or up.
"If the customer has the pennies, they can use them. Payments with debit or credit cards, or cheques, can also be to the penny. But if the customer is paying cash and doesn't have the pennies, the total will go up or down to the nearest nickel."
Presuming a uniform distribution of price endings, existing pennies are then worth 1.43 cents (you only spend them when the price is congruent to (0.03 or 0.04) mod 0.05).
