Moving Back Home to Canada

As the title suggests, I'm probably moving back to Canada this year (by summer or at the very least by Christmas) after living in Japan for more than 6 years.

Also, is there anything I should prepare in my current country of residence for making the trip back home? I'm thinking double copies of tax documents, international drivers permit, criminal record check of some sort. I have a few people who could help me with my pension lump-sum, but maybe I should go with a company?
Am I missing anything else? I'm a Canadian citizen, born and raised in Canada.

I'm planning to send boxes around March of winter clothes to my parents house, and I have friends willing to take a suitcase or two when they visit in May.

I've helped many a person with clearing their apartment to move back home over the years, but I never thought this day would come for me. I was dead set on staying in Japan until this last year. So other than essentially destroying the nest I've created, I'm wondering what I should work on to make the transition back home smoother. (I moved to Japan December 2019, so even though I'm moving home, I'm treating it like I'm moving to a new country again.)
