Regarding the following:
UPDATING REFERENCES TO EXTERNAL TECHNICAL
STANDARDS, SPECIFICATIONS AND CODES
Changes are also proposed to all Provincial Standards, which are incorporated by
reference into the regulation under the act, in order to reference the most current
version of specifications, codes, standards, etc.

Does this mean any "grandfather clause" will be obsolete?
How will this change effect current installations?
Will compliance to changed codes, specifications, etc., be compulsory on date of revision?
