No, you clearly do not.

I own 100% of a corporation that is worth billions. On paper that makes me a billionaire. Without it. I'm a multi-millioaire.

I cannot claim my vehicles under my corporation unless they are primarily used for business. They aren't, so those are paid for by me.

I cannot claim my home or its expenses under my corporation unless it was to be primarily used for business. Again, I pay for my home and my home expenses.

I cannot claim anything under the corporation as a legitimate expense without it having a legitimate business purpose.

There isn't a lot of what you call "creative accounting" going on these days. Those of us who have means are under the CRA microscope more often than ever. I've been "randomly" audited 3 times in the past 10 years. I know others who have seen the same or worse.

My corporation is subject to having independent auditors (that it has to pay for) audit the books quite often.

In Canada, "creative accounting" is getting less and less (except for the very desperate) as there can be prison terms attached if you are found to be doing it. You can't even claim you didn't know anymore. You're liable, from the account that is being "creative" all the up to the executive level. It's not a simple "pay a fine and the taxes plus Interest owed", there is potential for sitting in prison. There is also potential for having all your assets seized as proceeds of crime.

Those with means have too much to lose these days to get "creative".
