Wet and mold spots starting forming on the bedroom ceiling in my townhouse. I have owned it for 10 years with no problems until now and the strata contacted a roofer who checked the attic and said someone(previous owner) had run a telephone wire through the attic and in doing so pulled back the insulation and never replaced it. Water has now formed and pooled between the drywall and the vapour barrier. Is it possible for this much humidity to condensate through drywall that it is pooling under the vapour barrier?

Well, you figure. In the winter you have the heat on with cold in the attic. In the summer you have the opposite. If it is sealed tight, quite a bit of moisture could build up.
I don't know if homeowners insurance would cover that or not.
If the moisture has worked its way through, you will probably have to replace the drywall.
Hope it works out for you
Good luck

Is it near an outside wall on the lower side of the roof?
Ice dams are a common problem.
