As a small business owner, I basically look at how things work out at the end of the year. If there is money left over, then it's usually reinvested. However, a small portion would be put towards retirement.
On the personal side, because it's a corporation and I'm an employee of my business, like everybody else, I pay my taxes under my bracket. Basically, I'm able to use that for RRSPs, provided that my family is taken care of and that all the bills are paid. It's probably no different than yourself or what have you. The only thing is that I'm not a public servant. It's all private. That's all.
Does that answer your question?
