Hi, got AC flight from YYZ to ORD, few checked bags we have and our 2 year old.

We all have GE but never ever used before and no experience. There is a pre clearance after the security line? We go to GE Kiosk machine and then scan passports, answer the questions about food and then pick up the receipt and then? Do we have to scan our GE cards and passports both?
Also we have food, we will have our bags checked by CBP agents?

I have a stroller with a young child and I have 3 checked bags, I wonder if I will have to manage all this?




Thanks in advance for your answerS.
