We are not snowbirds but travel a lot. We debit and carry no more than $200 cash. It is really dangerous to do so.
If you use your Canadian account, let your bank know you are travelling, where and for how long. They will monitor your debit and credit cards for questionable use.
Hubby and I went on holiday and did not let the bank know. We were in the middle of a northern area and I went to get cash at an ATM. Our bank had froze our account. When I called they said $15,000 in 6 weeks was an unusual amount to be debited. We did not use credit only debit or cash. After I explained they unfroze our account again. It scared me as I knew there was lots of money and was happy they were looking out for our interest.
