As I said in response to Mr. Poilievre's question, I don't know what the pros and cons are.
The situation whereby one can have more than one million-dollar capital gains rollover—three, four, five of them—is one concern the finance proposals are addressing. If one had only one million-dollar rollover, that would have an effect, presumably, on heritabililty without more tax liability for a family farm.
As to your question, 90%—I was surprised when I looked at the numbers this past weekend—of farm businesses are incorporated. There are, then, already corporations.
The legal structures involved in farms are very complex. There may be one company that owns the machinery, another company or organization that deals with leased land. Unfortunately, we don't have the data to understand that. Whether one legal structure or another or a mix of legal structures is the most efficient way to organize this or that kind of farm, I simply don't know. I think it's an open question, one that merits some careful analysis.
