I play in a cross border Symphony orchestra. We play concerts on both sides of the border.
For the last 25 years or so it has been possible for me to go back-and-forth to play paying musical engagements in Canada. Apparently this is fine as long as I am not staying for an extended period of time, I.e. Coming across to play the gig, getting paid and going right back home again.
To smooth the path I have a Nexus card which allows for expedited custom processing on both sides. It costs $50 for 5 years and it's totally worth it.
I don't expect you will have any problems, but as others have mentioned you should definitely do your homework beforehand.
For what it's worth, I cross regularly from Port Huron Michigan to Sarnia Ontario. I work regularly in the Sarnia Lambton area.
Is that the International Symphony / Sarnia & Port Huron?
I filled in with them a few times back when I was a student at UWO. The univ's conductor (Jerry Summers) was also the conductor there at that time (mid 1990s.) They were fun to play with.
@Jason Hollar : Take the advice given by Bassdroid & others. Get the necessary preliminaries / paperwork done 1st. We *LOVE* excessive bureaucracy here in Canada, but so long as you tick all the boxes, it shouldn't be a big deal.
