Is it? I have a notice period of three months, so I figure if I were to try and switch jobs I would have to tell my future employer that I couldn't start any sooner than that. Else, I am potentially liable for any costs my current employer has due to having to replace me inside of those three months.

Yes, two weeks is pretty normal (in the US and Canada), but it's also normally not written into your contract, just a social convention.

I imagine your contract is binding (though I'm no lawyer and it may depend jurisdiction), it's just not a common term in my experience/the experience of people I know.
