The only safe way to keep your PR is meeting the RO. If you already don't meet the RO, you will have to take a risk entering and no matter which method you use, it is possible to get caught or to get a lenient IO or a strict IO. A lot depends on your luck.
The above means a lot, if one understand how difficult the decision to move to Canada becomes if someone entering Canada without meeting RO, so much of stress and torcher one has to bear that one who entering Canada meeting RO cannot even image. Not only that, you enter Canada without meeting RO and life is smooth there after, No, real hell starts after that, bank, health card, DL, job, sponsoring (Kids, Spouse, relatives etc), emergency travelling, CRA etc. for another two years or so make life pathetic. Every other day you spend in Canada with fear and frustration for another 730days. The one lie at border open doors of lies in your life, you have to manage all your lies and character for the rest of your life. So after all I would say is better to meet RO than live a life of hell in a beautiful Country like Canada.
