Thanks. Here goes:

"But.....OK you strapped the pipes in the basement but the noise still continues upstairs......." --> This noise in the basement was/is similar to the current one. Solid bangs, the type that copper pipe hits the stud. I packed in the pipes in the basement with insulation in between the brackets/studs/copper-pipes, and viola no sound at all.
"How about the other side of the living room wall and the "other" side of the LR ceiling ?" Other side of LR is fortunately a closet - Blessing in diguise - thru which the two pipes go upward from the basement. Thats where the maximum LOUD bangs are coming, so I can work on it even if I do a messy job of re-drywalling, and hence I will start there first. The other side of the LR ceiling is the 4th bedroom. FYI: When I walk into the empty 4th bedroom, at a specific location on the floor (carpeted), I hear the pipe vibrating even if I walk ther softly. Once someone has walked over that area, there is no vibration. Leave the room for an hour, then walk over the area, I can hear the pipe vibrating (to the beam or floor board) - So I know that the pipes in the problem area, are not clamped in properly. I would venture in the ceiling area, only if the closet wall clamping does not help - I am hoping by clamping the closet wall side, it will fix/minimize the banging. I will certainly be very scared to work on the carpeted floor area, and would rather work on the ceiling underneath from the LR area, as I think it will be easier.

"WHY IS IT VIBRATING ?........even after ..." Dont forget, I clamped the entire basement area ONLY, and hence that area is quiet as a feather. If the pipes are lose in the upper area, it wont help from the basement clamping, would it?

I am really confused. I THINK I HAVE MORE THAN ONE PROBLEM. Please hear me out:
When I flush the problem toilet, I get the banging in the LR wall. When I use shower / sink in the same problem washroom, I get periodic banging (for almost 2 hours after), and this involves hot and cold water pipes. From all this, I gather, aside from the pipes being lose, I have a WATER PRESSURE PROBLEM, and maybe copper pipe thermal expansion problem, as the noise also escaltes with use of hot water ???????????????
"Was this plumbing installed by the "owner"......sometimes design/install defects can create similar problems......" Ours is a builders model home in Toronto, and highly doubt if the owner did any plumbing work, although the guy looked like he was a handyman type - I have never known anyone in Canada buying a new home from a bulder and doing such work on his own ?????

Water hammer arresters, I have heard bring in their own problems, hence I'd like to stay away from that.

Sorry for being so long, BUT PLEASE ADVISE, and THANKS.
