Paddle4Hike: "I will see if I can find the obscure website reference that I came across when I did my first solo in 2017. It said, and I confirmed it after arriving in MN, that if your "home state" for your canoe did not require it to be registered, then you did not need a MN registration.
Will post it as soon as I find it.
Enjoy your first solo! What is your planned trip?"
Here is the link to MN 2018 statute saying it's not required in MN if your state doesn't require it.
