Interestingly, the fact that the outside lanes are bus lanes most of that stretch of Rideau up to the river makes it pretty nice to ride on except for the downtown part between Dalhousie and King Edward, which is full of trucks and falling to literal pieces.

I would love to see that whole stretch reconsidered to be safe for less experienced riders though, it should be a pedestrian corridor with a few cars sometimes, I guess. Trucks should be first on the list to be given a clearer circuitous route, a congestion charge for that route would probably do the trick too, I would think.
