Exporting car from California - DMV rules

Can anyone who exported their car from California to Canada confirm the following?

  1. How did you return your registration plates and cancel your registration renewal with California DMV?

  2. Did you fill certification for exportation before exporting the car - https://www.dmv.ca.gov/portal/dmv/detail/vr/export ?

  3. Any forms (like change of address) you filled or sent to the DMV for the export/import?

@ashwin @vik Could you provide your input?
