Driving Across Canada to move

So as my title states, I'm attempting to drive across Canada in order to move to Alaska from the lower 48. I'm a US citizen with a clean record and have my passport card. I want to bring my car up, but I've never traveled to Canada. (Car is in my name and insured under my name as well.)

I was told I would need to fill out a Notice of Intent to Travel. From Canada's own travel site , it just looks like this is needed for Air travel? So I'm confused. Do I still need this? What else would I need?

I appreciate any advice.
