The photo below got me to wondering what the impact of all those tourists you see on the boats was to the 1000 Islands region.
The most recent report on the subject was from 2011. In it the 1000 Islands Region was responsible for generating $456 million from the tourism industry and $56 million in state and local taxes. All currency in US dollars. I can only assume the figures are similar for Canada. That is a lot of boat tours, resort rooms, restaurant meals, souvenirs and other tourist spending.
