You will also have 20 days to get the T1 form signed off by an official source.
T1 form is the conformance letter saying that your car meets all the FMVSS ( Motor vehicle safety standards) - Daytime running lights / Conversion of the speedometer to KM, airbags, anchors for child seats...etc
Canadian Tire will perform the inspection and stamp the T1.
We need to T1 stamped before MTO will issue plates for the car.

I might have skipped a few things, but that is the bulk of the work

I have also heard about import duty on Japanese made vehicles as well. You might have to check into that as well.
