For Canadians travelling directly from Canada to Bermuda and for Canadians returning directly to Canada from Bermuda, entry and exit requirements demand only that the traveller be in possession of valid official photo identification (such as a driver's licence) and proof of citizenship (such as a Canadian birth certificate or Canadian citizenship ID card). For entry into Bermuda, proof of a valid return or onward ticket is also required.
Note: It is recommended that travellers carry a valid Canadian passport, which would likely be required if travel plans had to be changed and involve travel through another country
