Calais is in Maine. Which is part of the United States of America. This ArriveCAN App you speak of is a Canadian Proprietary System. In having said all that, try your luck at St. Stephen New Brunswick Canada. Specifically, "Ferry Point" or "3rd Bridge." Good Luck.
If its the one on International Avenue it's called "St. Stephen 3rd Bridge"
