The most prevalent versions of the coin show a common loon, a bird found throughout most of Canada, on the reverse and Queen Elizabeth II, the nation's head of state at the time of the coin's issue, on the obverse. Various commemorative and specimen-set editions of the coin with special designs replacing the loon on the reverse have been minted over the years. Beginning in December 2023, a new version featuring King Charles III entered circulation.
The coin's outline is an 11-sided Reuleaux polygon. Its diameter of and its 11-sidedness match that of the already-circulating Susan B. Anthony dollar in the United States, and its thickness of is a close match to that coin's thickness. Its gold colour differs from the silver-coloured Anthony dollar; however, the succeeding Sacagawea and presidential dollars match the loonie's overall hue. Other coins using a non-circular curve of constant width include the 7-sided British twenty pence and fifty pence coins (the latter of which has similar size and value to the loonie but is silver in colour).
