The tugboats here remind me of The Beachcombers, the longest running drama series in Canadian tv, from 1972-1990. I used to watch it but all I remember was the unpalatable character Relic, and how most episodes were about chasing after logs that got away from logging barges. Can't get more Canadian than that. Except maybe if it was about harvesting maple syrup. Or making ice wine. Or something about beavers.
