I am not sure if I completely understand "If you pass the work permit application online"
Can you give me the link to this...
This only depends upon where in the world are you located. Putting it plainly it is INCORRECT to assume that if you applied online, your application will be processed "INSIDE canada". You are still catered by the visa office of your home country or the one you have been legally permanently residing.
Applying online only makes it a little faster in general. Time estimates on the official CIC link pretty cleanly explains this.

The one month time only applies to people who applied from INSIDE CANADA.
For those applying from OUTSIDE of Canada, processing times are viewed by visa office.
