It was a fun tour with beautiful views. Lasted about 75 minutes with a quick stopover at dock in Gatineau.
Leave plenty of time. You'll need to park at the National Gallery, and it's a long walk down to the Rideau canal locks
The guides read word for word the sights we were viewing from the boat. I appreciate English is not their first language, but their reading skills were atrocious! Very unprofessional. Sights were beautiful, but we were left with so many questions about what we saw. No off script commentary at all.
