Here is an option for much more reliable source of information for the people really interested about the real cut off date and month if its known and intentionally kept away from public.
I'm copy pasting a segment from dpenabill post.
...for whom the date is important, should write a brief request to their Member of Parliament:
This should be a request that the MP either:
-- advise them when (more specifically than "in approximately a year") the government will in fact make the revised provisions in the SCCA in force, or
-- if the MP will ask the government, during the Parliament's Question & Answer Period, why it has not made the coming-into-force date public given the impact it will have on many thousands of PRs who are just now becoming eligible for a grant of citizenship
Including, in the request to the MP, a succinct statement about why the coming-into-force date is personally important might be a good idea. Keep it brief. Do not entangle this request with advocacy for changing the law (such as, for example, to give credit for time in Canada on a work permit).
