I canoed the Noire river in western Quebec near Ottawa back in 1999. It was about 130 miles of river through the wilderness taking 6 days (including one rest day in camp). Lots of rapids. That was my biggest and longest canoe trip.
I found this video online of the river:

I highly recommend this river. Here is a description of the river and rapids that I found, but there is a book you can get as well

Take out
Portages around most rapids, but not all, including some CII tech's.
Some of the class I's become class II tech's under certain conditions.
All portages relatively easy, with the exception of Mountain Chute. The long portage is "from Hell", and the short portage is no fun either-sideways up hill, and then stringing ropes to get you and gear down a very steep drop. Small put in at base of falls, and above 1km of rapids you can't read in advance.
