RRSP vs Corporate Investing

Is it better to invest inside our medicine professional corporations or direct the money into an RRSP?

As I have come to realize over the last several years, readily available investment tools such as the RRSP have considerably different optimal utility points for physicians compared to the general public. In the case of RRSPs, for example, making contributions every year may not be ideal, particularly for the high net worth physician who is nearing or exceeding the $500k mark inside their RRSP.
