Last release from CBSA:
The Canada Border Services Agency (CBSA) reminds all boaters that crossing the border for recreation or tourism is currently prohibited.
Boaters are still permitted to navigate across international waters if needed, but are not allowed to enter Canadian territorial or boundary waters for discretionary, leisure (non-essential) reasons, including entry for touring, sightseeing and pleasure
fishing.
Boaters who enter Canada without reporting to the CBSA (including for the purpose of refuelling) may face severe penalties, including monetary penalties, seizure of their vessels and/or criminal charges. The minimum fine for failing to report to the CBSA upon entry to Canada is $1,000. Furthermore, non-compliance by foreign nationals may affect their immigration admissibility and ability to re-enter Canada in the future.
Conditions for a Reporting Exception
Persons who enter Canadian waters are not required to present themselves and report their goods to the CBSA if they:
do not land on Canadian soil and do not
anchor, moor or make contact with another conveyance while in Canadian waters; and
do not disembark or embark any people or goods in Canada.
Persons who leave and re-enter Canadian waters are not required to present themselves and report their goods to the CBSA if they:
did not land outside Canada and did not
anchor, moor or make contact with another conveyance while outside of Canadian waters; and
did not embark or disembark any people or goods while outside Canada.
