do small businesses in Canada charge in USD or CAD?

[Davidl]

The companies that are based in Canada but selling to USA too, they typically sell there goods online to Canadians in USD and convert it over to CAD. Is it possible to charge items in USD in Canada?

For example a Canadian brand sells hoodies online. The Canadian site shows 59 USD and the american shows 59 USD. Would it be the other way around Canadian site sells
the equivalent to 59 USD in CAD or does it not matter too much?

You can charge in whatever currency you want for the most part. Right now, there's about a 10% premium on the Canada dollar; the difference isn't huge on a $60 item, so they're probably pricing in USD to avoid the currency conversion costs that a lot of card processing firms want to charge to get the transaction into the type of currency the owner of the site can use to pay bills.
