What?…… this is all new to me. I have never heard of all this…. I have gone to Canada multiple times and just called in when entering Canada waters….. that’s it.We also were told to fly a small yellow quarantine flag until registered with Canada border control, then change it to a small Canadian flag as a courtesy/let them know we are registered. We planned on going 2 weeks ago, but smoke hindered that plan. So next summer it is. Also, figure out rules about alcohol. If asked, we were told to announce we had "normal ships stores" aboard. This is from a very experienced Captain who has also done the loop.
I highly recommend you call customs ahead of time and figure out the rules for yourself
