PGWP for 2 differents diploma ?

[Frollo888]

hello everybody!

I want to attend a 1 year diploma post secondary program
starting in March 2018 until March 2019

and then I would like to attend another 1 year diploma post secondary program in another school.
starting in Sept 2019 until Sept 2020

If I apply for a PGWP after my last diploma, will I get a 1 or 2 years WP?
they will count both years of studies or just the last one because of the gap in between them?

(both schools are DLI so I can apply for the pgwp)

Thanks in advance!!
