If you don't mind traveling a little each day, you could stay in the US . About 50 miles south of the city of Montreal is Plattsburgh, NY. If you were to take route 9 south to a place called Keesville, NY you will find some small Mom and Pop motels. When I worked in the Plattsburgh area a few years ago, I stayed in an efficiency; bed room small kitchen and a bathroom. $100 per seven day week in the off season. the season doesn't start until June.
Hope this helps.
