Thanks for looking.
The below photos are from the area of the basement where, up until recently, sat an oil burning furnace that was originally installed as a coal burning unit. The house was built in the '30's (Montreal), and my mother, the current owner, has owned the building since the '70's. The material was already in went she bought the house.
Whether it is or is not asbestos, please supply a little bit of background info, if you can (i.e. I have seen that before, I am a specialist, etc). Thanks so much! More pics available if needed.
