I'm in Canada and it's the same. My salary agreement says I get paid X for Y hours per week and is very vague about how overtime is treated. There is a mention that there may be "expected overtime" required on an occasional basis. I have never received compensation or time-off-in-leiu for overtime worked and during term (i work for a university) it's expected that I work 45-50 as opposed to the 35 that was agreed upon. 35 hours per week is summer only, and then I'd be lucky.
