RPN to BN?

This grade scale for Canada shows a 69 to be a C+. (Astonishing that this is standard for a whole country! Every professor in the US sets their own grade scale). I don't know if that's good enough to get you into a BN program. Part of it might depend on what grades you got in which courses. Did you do well in the science courses? I can tell you that BN programs are tough, and should be. People's lives depend on the ability of nurses to see problems in patients, including side effects of medicines and treatments, and to understand the interactions among chemicals in medicines. 

a few years of real experience and you'll likely be accepted

I would first verify with your school officials that you are actually on track to graduate.  I don't know about Canada, but in the US an average of 69 would be under 2.0.  A minimum of 2.0 is necessary to graduate.
