Hi there
Given that a person has a legal status all the time. It depends on the job letter. In my case I was on wage subsidy for about 3 months(I worked 9 months and was not working for 3 months) and when I asked my employer for job letter they just mentioned the start date of my job, number of hours per week and my current status(working), etc. So that adds up to one year.
Which means I was still employed for those 3 months. Also, I checked my pay stub which added 40 hours per week for the period of time on wage subsidy program even though I was getting paid 75% of my wage.
I got my ITA and will post about any updates.
Enjoy your life and say waheguru.
