Their conclusion: just move to the US, it's easier.
Previous startups I have worked for in Canada have all gone south of the border to raise either VC or Angel funding, so I suspect that this problem is somewhat over hyped. That said, everyone likes to remove friction (and accounting/legal costs) from raising money, so the change in law is a good thing.
As another aside, a Canadian company can multiply investment (certainly at the level of Angel investment) by as much as three times thanks to various Canadian R&D programs (IRAP and SRED), and Canadian investors usually qualify for the lifetime capital gains exemption, which can make an exit even more appealing (who doesn't love a tax break?). So there are some good reasons to invest up here.
