My wife and I took a visit to fortress Louisbourg while I was on business in Cape Breton and it was a very interesting trip. My wife was a history major in University so it was extra special for her, but even for me (a layperson at best where history is concerned) it was a thoroughly enjoyable experience.
The weather wasn't great so we didn't spend as much time there as we otherwise would have, but still we got to witness the people in their period attire performing the same tasks you would have witnessed them performing in times of old.
One hint is if you're going, try not to wear red (or do if you like that kind of thing) because the guards are not just in period clothing, but perform as if the British are still the enemy and stop those wearing red in fear they are either British sympathizers or worse, British spies.
This is pretty out of the way but in my opinion, well worth the time to get there. Check it out if you find yourself on "The Cape".
