Not sure if there are any other members on the forum from Manitoba, but if there are, there is an upcoming seminar being put on by the province on Invasive Species. It is specifically geared towards float plane pilots. It's at the Canalta Hotel in Selkirk on Wednesday November 25 at 7 pm. The seminar is free and there will be coffee, snacks, etc.
There will also be a meeting after the seminar to gauge interest in the formation of a seaplane pilot association in our province. For more details, you can pm me.
