Carrying cash from United States to Canada
Two separate rules apply to any cash journey: one where you leave, one where you arrive.
Do you need to declare?
Yes: and on both legs of the journey. Leaving United States, U.S. Customs and Border Protection requires a declaration above USD 10,000. Entering Canada, Canada Border Services Agency requires a declaration above CAD 10,000. The two rules are independent: satisfying one does not satisfy the other.
Travelling as a family or group?
The threshold applies to your combined total, not per person. A family of four each carrying a little under the limit is still over it, and splitting cash between travellers to stay under does not make it legal.
The two legs
| Leg | Limit | Form | Authority |
|---|---|---|---|
| Leaving United States | USD 10,000 | FinCEN Form 105 (CMIR) | U.S. Customs and Border Protection |
| Entering Canada | CAD 10,000 | Form E677 (Cross-Border Currency Report) | Canada Border Services Agency |
The same reporting duty applies when leaving the United States.
Declare CAN$10,000 or more in currency or monetary instruments any time you cross the border.
If you do not declare
United States: Seizure of the currency and possible civil and criminal penalties.
Canada: Seizure of the currency and monetary penalties.
There is no limit on how much you may legally carry in either direction, the duty is to report it, not to keep under it. Failing to report is the offence.
Currencies
United States uses USD; Canada uses CAD.
