ELI5: What is preventing Toronto from acquiring an NFL franchise?

Toronto is the 4th or 5th largest city in all of North America. It's a major metropolitan area. It has a sport team in all other North American major pro sports. What is keeping Toronto from getting an NFL team?!

Football is the only major pro sport that has a viable and independent league in Canada. Toronto already has a CFL team. 

In order for Toronto to have an NFL franchise, they'd have to figure out how to convince the NFL that they could have two viable pro football teams. Toronto is big but it's not that big. They could, of course, shut down the CFL team, but this would likely anger fans so badly that the new NFL team would be doomed from the start.
