Using US Dollars at Niagara Falls: Canadian vs. American Side

Currency Guide for Niagara Falls Visitors

Canadian Side (Ontario)

Official currency: Canadian Dollar (CAD).
Many tourist-area businesses (hotels, attractions, duty-free shops) accept USD, but often at unfavorable exchange rates. Change may be given in CAD. For better value, exchange USD to CAD at banks, ATMs, or currency exchanges.

American Side (New York)

Official currency: US Dollar (USD).
All businesses accept USD freely. No exchange needed.

Practical Tips

• Use credit cards (no foreign transaction fees) for best rates.
• Carry some CAD for small vendors, parking, tips on Canadian side.
• Check current exchange rate before travel.

Bottom line: USD works everywhere on the US side; on the Canadian side, it's accepted in tourist zones but CAD is smarter.
