Out of curiosity, have you found that having a PE licence has been useful at all in your work?

I studied Software Engineering at an engineering school accredited by whatever organization regulates the practice of engineering in Ontario. I remember at a few points in the program, they made a point of saying that once we graduated, we could apply for a licence (after we spent time apprenticing), but it was never clear to me why having a PE licence would be useful. I don't know anyone from my graduating class that's bothered to apply for a licence either.
