If you create a profile without meeting the year of continuous full-time work experience then your profile will automatically be deemed ineligible. That is, your profile won't be in the pool.
Basically work experience is:
TAship in the same Canadian university for the following periods
Jan 2015-Apr 2016
Aug 2016-Oct 2017
average weekly hours: 13 approx
Total hours: 1600 approx
Would the break from May-Jul 16 affect eligibility? Is it okay to create a profile with continuous work experience and on receiving ITA, submit a letter of explanation regarding the break?
