Niagara Falls overflight

Thanks to everyone who responded about Niagara overflights. I haven't gotten to
the airport yet to get the A/FD, but it sounds like the procedures are spelled
out pretty well.

One question I do have is regarding Canadian airspace. Looking at the pictures
and the info I found on the web, it looks like the oval racetrack pattern takes
you over both sides of the falls. This is great because you get a much better
view than I was expecting, but do I need to do anything special for entering
Canadian airspace?

Thanks,
Eric
