This week, I had the opportunity to visit the Rideau Canal in Ottawa. It is one of the best-preserved 19th-century North American canals, built partially as a defense should the US block the St. Lawrence Seaway.
This is my 48th World Heritage Site visited, so I'm up to 5.3% briefly before more are inscribed later this month. Since I've visited none of the candidates, that will drop my percentage back down again.
I was in Ottawa 15 years ago, but I don't remember making it to the canal. If I come across the pictures that prove otherwise, I'll update my World Heritage page to reflect the visit.
