There is no single reason. It ranges from our regulatory system, which today is...“cumbersome” would be a polite way of putting it. The Canadian market is a tenth the size of the U.S. market, and they have an easier regulatory system down there, so you know where industry will go. It's a no-brainer.
That's one reason, but not the only one. The VC side of the coin, of course, is important as well. We've established very successful companies that have been bought out by others and moved south of the border.
