I'd have to ask my accountant if I've contributed to CPP, but I know I haven't paid in cent one to EI in close to a decade now, which spanned a period both as sole proprietor and, post incorporation, as president. I don't believe I've made any CPP contributions.
I have, however, maxxed out my RRSPs.
Hell, for all I know I may have some unused EI contributions that I'd made ages and ages ago and never drew on.
