I think They are only prioritizing HCCP and HSW with LMIA inside applicants. The site states that when you apply for a work permit outside canada, it should be filed ONLINE. There is no option for HCCP and HSW to apply for a work permit online, except to those inside canada with LMIA.https://www.canada.ca/en/immigration-refugees-citizenship/services/coronavirus-covid19/foreign-workers.html#outside
Good news for all.. check above link carefully. updated on 9th feb 2021. HCCP and HSW comes under priority programs now.. its a great news finally for all of us. Specially 2019 applicants ist..
If you extend or change employer here, and you have LMIA, you will send your work permit application online.
