I am a US Citizen who recently married a Canadian and we have a 3 month old baby together. We don't currently have any application for my Spousal sponsorship yet but we are going to start the process soon. I have been coming to Canada for a few weeks and then returning to Buffalo for a few days...rinse and repeat...However, we now both have to cross the border together and with the child. I don't forsee much of an issue crossing the US border, My citizenship covers me and my wife has ample proof of her intent to return to Canada. However crossing back into Canada concerns me. I can envisage the CIC asking some questions about my intent to return to the US, especially knowing I have a wife and child in Toronto. Any advice for making the crossing as trouble free as possible?
