Yes but there are big ranges. Size matters as well. Their website lists the ranges.
The best thing about this package service company is that it is right at the pacific crossing so you can parh your car in Canada and walk across avoiding the boarder line for cars.
Most packages are not weight out size based but based per package. I've been going for around 5 years and only been charged more than minimum one time.
