As DW has Family in Canada, we used to be crossing frequently. Going into Canada has never ever been an issue. We have passports ready and answer questions and are gone. This true for us both at Sarnia and Windsor. But returning to the US? Even with special credentials, it has often been a hassle. Much more so at Detroit than at Port Huron, but it is still enough different that we will go to Port Huron if it is not a great inconvenience to do so.
I know you did not ask, but Buffalo and Ft. Erie have never been an issue.
Of course we have now not done any of this for a year......
