I can't give you a definitive answer. I would assume that if you're a salaried employee, they will consider you at a lower risk of being short on hours assuming your income information (T4s, NOA) match what you're salary letter should be. That is, if there is a mismatch between your stated salary and actual income earned, they will likely dig further to determine if you didn't work full time for the entire period. In my experience (my own application), since I was a salaried employee, I only provided 2 recent pay stubs if I recall correctly (I had no issues with my application).
However if you are an hourly paid employee, then you are probably at a higher risk of being out of compliance with the hours requirements due to the nature of work, and they may take a closer looks at monthly paystubs to ensure eligibility under the rules.
