If you're not incorporated, you're begging to be taken to the cleaners. No Canadian in their right mind would earn over 70k a year without incorporation.
If you're not incorporated, DO IT NOW. You'll still have to take the tax bite (buy an asstonne of RRSPs, the deadline is coming up real soon now!) but you'll be set up right to move forward and grow.
In my case, income comes into the company as a result of consultancy or partnerships. Every penny goes directly into the corporate bank account. I let my accountant handle all of the detail work but the gist is that the gov't doesn't give a fuck where its coming from so long as they get their peice. You can claim any taxes you have to pay overseas and get a credit against canadian tax (to a point).
If you're making $150k a year, there's no excuse to fuck around. Find a lawyer, get incorporated, find an accountant and do it up right. You'll be glad you did.
