I've heard that r12 insulation for a basement is enough and there's minimal difference between the two. Is this true?
Read my previous posts on how to insulate your basement R12 Is a joke when it comes to insulating anything / R22 is the Min for me in a Basement.

R20 is the norm its almost double the insulation factor
This is not true, R20 will make a big difference, also check with your local building dept in Oakville you must insulate to a min of R20 on a finished basement.
