Well, your best bet is to find a local competent electrician (one with good references) that you can work with.

Not enough details on your house to give you much advice. If this has been renovated, look for signs that someone less than professional touched the wiring. Start at the main panel. Look for signs of knob and tube (not necessarily bad in its own right) that has been hacked on. Things that look sloppy, usually are hiding other defects, etc...

Thank you Ron. As I went to search, I came up with this Electric Contractors Muskoka. They also have service centers at Barrie, Orillia. They were voted ‘The Readers Choice Best Electricians’. I might get in touch with them the next day and get the work done with. The internet says that they are also a pro in this knob and tube wiring replacement. So hopefully they would be able to trigger some modifications done already and if issues are prevalent, they probably would be able to rectify.
