This sounds an awful lot like political talking points without any substantiating evidence. Most tech startups on this site don't overlap with any of the big regulated areas you've listed. It's also the case that you do not see new startups in most of those areas in the US either.
Most startups avoid these markets for an extremely good reason, they are well protected from competition. Every company that's tried to enter the regulated Canadian markets gets shut down pretty quickly either by bankruptcy, lawsuits, or forced acquisition. It's particularly brutal here. What we have in Canada can no longer be described as capitalism. It is totalitarian corporatocracy.
