We welcome our Canadian brothers and sisters with open arms. My cofounder came from Waterloo and together we built a good company with good jobs here in the US.
You should let the border guards know ;) the last time I got a TN my immigration attorney told me "honestly, you're lucky you're white, so you shouldn't have any problems."

Canadian TN packets are adjudicated at the border, by a border guard, in person. The immigration attorney was conveying experience with the adjudication process of comparable packets as a function of visual appearance of the applicant.
