Thanks ... do you know if they check work hours or other details
Dunno...
Why would you care to know anyway?
If you worked 20h or 60h a week somewhere, both would indicate that you were in Canada in the first place, and that'swhat IRCC wants to know.
The work history is NOT considered for IRCC's decision in your application, it's purpose is simply to strengthen your physical presence claims. Nothing more.
Just make sure your work history is accurate and don't worry about it.
