I often just figure out "where is 40 miles" from wherever I stopped, then Google that area for "campgrounds". You can use the Google maps with the Bicycle option, it will give you a sense of what roads and about the distance. I then use RideWithGPS for the actual route planning as I can dump the route to my Garmin cycling computer. Dont forget to ask the group you are a part of for advice.

Also look at the P'tit train du nord" trail just north of Montreal, very popular bike trail, southern terminal is in Saint Jerome, just north of Montreal. There are something like 6 campgrounds on the route.
