Marrying US girlfriend

I am about to marry my US girlfriend and we decided to live in Ontario after. I am going to sponsor her.
Just wondering if I'd have problems crossing to border to US to visit her while her sponsoring application is in process. I have no intention to immigrate to US.
Thanks

As long as you show documentation of her application, you should be fine. This should be enough (along with your normal evidence that you have sufficient ties i ncanada) that you aren't coming down to stay.

Thank you
