Most Canadian traffic signs use similar symbols to U.S. signs, although some may be posted in different colors. It is the responsibility of travelers to satisfy U.S. customs authoritiesof their rights to reenter the United States, through some form of identification. Re-entry can be simplified if travelers keep a list of all purchases, have sales receipts and invoices handy and pack purchases separately for inspection. Families may combine their personal exemptions. Articles exceeding the exemption will be assessed for duty.
Excess articles are subject to duty and taxes.
The monetary system in Canada is based on dollars and cents, as in the United States. Exchange rates do vary, so use Canadian money in Canada to avoid exchange problems. While U.S. money is usually accepted in Canada, it is easier for visitors to exchange their funds or travelers checks for Canadian dollars at any Canadian financial institution or exchange booth. Using credit cards will give you the best exchange rates without a fee. It is recommended that visitors take more than one kind of card.
