The Bank of Canada Museum
Unfortunately, the Bank of Canada is renovating its building, and this excellent museum is closed until 2017, although according to their website it will be worth the wait. Until then, you will have to satisfy yourself by visiting the Royal Canadian Mint, which is a short walk away.
A must see!
I visited the museum before they closed down for renovations, the new museum however will be larger and with more modern displays. Once called the Currency Museum, they hold the most sought after coins and banknotes in the best conditions known. Ex; They hold the last Canadian penny minted, the first silver dollar of Canada from 1911.
Well worth the visit,
