Canada did away with pennies: http://www.mint.ca/store/mint/about-the-mint/phasing-out-the...

From Wikipedia:

Production of the penny ceased in May 2012, and the Royal Canadian Mint ceased the distribution of them as of February 4, 2013. However, like all discontinued currency in the Canadian monetary system, the coin remains legal tender. Once distribution of the coin ceased, though, vendors no longer were expected to return pennies as change for cash purchases, and were encouraged to round purchases to the nearest five cents. Non-cash transactions are still denominated to the cent.
