Saw several strange looking planes land today. They looked like a typical crop duster but were on floats/pontoons. I think they were these https://airtractor.com/aircraft/at-802f-fire-boss/ . Guessed at the time they might have been for fire fighting. The Ontario government gave up on this type of fire fighting aircraft a long time ago. This is the standard firefighting aircraft employed by the Ontario government https://en.wikipedia.org/wiki/Canada..._(cropped).jpg .
