It's muddy, but his net worth is estimated at $1-5 million OR $25m+. So either way he's not mega-rich, somewhat to extraordinarily well off for a career politician no doubt. Admittedly, I only spent about 15mins looking into it, but everything I saw essentially says the same thing:

• Net worth ~$1-5 million OR $25million+(hard to tell what's legit here, there's not much that doesn't reek of speculation).
• Income sources are political wages, consultant firm, property(ies?), book royalties and investments.

That's pretty much it. I'm not even sure I trust either number to be factual, there's no sources stated for figures. I'm not a Tory, I firmly believe that they're the antithesis of what it means to be Canadian. If anyone can firm numbers, I'd love to see them.
