Will officials stamp on my passport?

[htwo0]

I'm holding a B1/B2 US visa issued in Vancouver, but I never use it before.
My PR card expired, and I'll fly to Seattle and enter Vancouver by private car.
My understanding is that I'll get an I-94 card and the US entry stamp at Seattle Airport, but US/Canada Border Service won't stamp on my passport.  Is that correct?

I'll leave Vancouver a month later.  I'll take a bus this time.
At the Canada/US border, will Canada officials put an exit stamp on my passport?
Will US officials put an entry stamp on my passport at the border?
Will US officials put an exit stamp on my passport at the Seattle Airport?
