Thanks for your replies. I'm just going to speak to an immigration consultant to get my answers. The consulate never answers their phone or returns messages or emails. I've been trying them since Jan 4. I've even called other locations. I have tried the US Customs office at Pearson but their phone rings but is not answered no matter what time or day you call. Their recording states their hours but I guess they don't extend to answering the phone. I called them since they gave me the paperwork
As for the customs questions, they're not the issue. However, I wasn't asked any questions nor allowed to speak this last time anyways.
I always have a notarized permission to travel alone with my daughter letter whenever her father isn't with us. You're right though it's hit or miss if you're asked for it. I'm usually asked for it upon our return to Canada rather than our departure. I find this odd as I am bringing my daughter BACK home, not trying to take off with her. It's just easier to have it and although it's not necessary to notarize it, it just makes life so much easier and less questions asked.
I think I will just go to the airport and ask my questions if I can't get answers elsewhere

Thanks again.
