A little more information on why I am confused. The border crossing I went to is small though there were four officers there. We were the only people going through at the time. The person came out to my truck and asked a few questions that we replied very honestly, scanned our passports and sent us on our way.
There was no stamp or anything to indicate that should be able to stay longer so I went inside and explained my situation and asked if they could stamp her passport so she could stay for another 6 months.
We had a polite conversation lasting a few minutes which at times involved all four of the officers there.
The conclusion of which was that she would have to leave as scheduled and that they had rules to follow and it was not their discretion to allow her to stay another six months that they were unable to do that and that was never done.
I thanked them for their time and left fully expecting that my girlfriend would have to fly back to Germany.
Later she called an immigration lawyer in Vancouver that speaks German and he said something similar to what I've read here that if you cross in and it's not noted on your passport you have six months. I also read this on other threads of this form.
There's absolutely nothing noted on her passport.
I'm a bit confused
