Emphatically concur with comments recommending seeing an experienced, reputable Canadian immigration lawyer as soon as possible.
Time within which you must make application for leave to appeal is 30 days.
At the least consult a lawyer . . . this alone might cost $300 to $500.
Beyond that, what your best course of action from here is depends a great deal on all the particular facts and circumstances in your case and in your life for the last many years.
I understand the drive to rail against the system in these circumstances, but your attention would be better focused on assessing the situation, identifying potential approaches to take, and taking actual steps in the direction you deem is right FOR YOU, in your situation.
Since I think it would be far better, if not imperative, to consult with a lawyer, I will not offer any concrete ideas about where to actually go from here, whether to appeal, make another application, or such.
But I will offer one example which should illustrate how the particular facts of YOUR situation are critically important:
There is no one general rule about rushing to apply again before the revised requirements come into force (take effect); for example, if you have been living in Canada the last six years, actually present more than 1460 days during these six years and in at least four of the preceding six calendar years you were not absent from Canada for 182 or more days (for each of four calendar years), and you have been filing a Canadian tax return as a resident of Canada, you already qualify under the new law . . . and you might actually sail through the process if you wait to apply under the new law (even if you get RQ'd it could, probably should go quickly . . . unless CIC has some reason to suspect you have been living abroad during the last several years). I am not suggesting this is what you should do. I am outlining some very specific facts which might induce you in this direction. Other facts could easily push you in another direction. Given the current situation, again at the least a consultation with an immigration lawyer, who can review all the relevant facts in confidence, is the best immediate action to take.
