As you’re aware, PEI and NL have announced changes to the Atlantic bubble. All travellers into these two provinces, including New Brunswickers travelling for work, should contact the appropriate provincial government to determine how those changes affect them, and whether any registration or pre-approval is required.

The announced changes do not affect New Brunswickers returning home after working in those provinces. For information regarding the rules in other Atlantic provinces, visit:
