If you didn't know, pulling your drain plug is mandatory within Alberta when transporting boats:

and should be noted that last year they were giving people a warning for this, and this year they will be fining for it (I spoke to the invasives person who indicated that they're not giving anyone anymore warnings). Particularly important with Whirling Disease in AB.
