The number of hours MUST be stated on your Proof of Employment/ Reference or Experience Letter, it is part of what the IRCC insists to be included. So what you'll do is that you'll include a range, meaning "MatrixCc worked 20-30 hours weekly" (or whatever your range/average). And NEVER leave your HR to write the letter for you, because IRCC mentions some important info the officer needs to see and not all HR departments are aware of the requirements. You prepare your letter yourself, include the hour range, the pay, your title, your job duties/responsibility that aligns & matches with your NOC, signature of the HR should be NOT in black pen. (blue or even red) , header with the company's name, address, contact info, recent date, then request the HR signature and approval. I had to tweak it a few times until I reached an acceptable copy.
This is what I did:
First page : Letter of Explanation; I stated all the documents included in the (combined) PDF
Second page: Letter of Explanation that matches my EE profile and what IRCC is looking for in am Experience letter.
Third page/section: A copy of my Google Sheets (remember how I used to track everything). I included a copy of the pay dates, hours and title columns. The officer doesn't have time to look at every paystub and do the math. You do the heavy lifting because they won't have the patience to do so. I included a breakdown of the hours and the total.
Forth page/section: ALL paystubs (I had almost 3 years of experience at the time and I included every single paystub).
Fifth page/section: Your T4.
I combined and compressed all the 5 sections in one PDF and uploaded it the proof of experience section for this job.
Hope this helps.
