Vahiguru jee ka khalsa vahiguru jee kee fateh!
I can't claim to be a spokesperson for the Gurdwara or the collective sangat who attends the gurdwara however this post has been brought to my attention and I will try my best to answer.
Firstly, I think we can all agree that peshis in front of the Punj Pyare are to be kept gupt (unless in the rare occassion there is a larger overarching interest, like the safety of a person, or larger Panthic interest that Singhs doing seva have to determine for themselves).
But I'm not sure what the purpose of such a post is besides creating controversy and dubidha. If the poster had a genuine concern, s/he could very easily go to the website and contact the gurdwara directly (all you had to do was google "gurdwara tapoban phone" and you would've found it. This type of exhibitionism is frankly a reflection of immaturity or something worse.
I personally am not aware of anyone who does seva in the Punj Pyare divulging information outside of the amrit sinchar. That having been said, if there is such a concern, the proper approach is to raise it directly or come to the sangat and raise it. Even if it were true that someone was guilty of such a mistake (which I'm not aware of and doubt would be true), how would it reflect on the entire sangat at a gurdwara? Wouldn't that individual be blameworthy alone?
I don't intend to reply further to this thread and would suggest it be closed as such discussions don't lend themselves to online forums. If you have a concern, you are most welcome to visit the gurdwara sahib or alternatively you can call 416-871-0182 and discuss it.
