I know that ECA is not required for Quebec Skilled Worker. I want to apply this year for Quebec Skilled Worker and I need some help for what kind of docs I need to collect.
The preferred choice is to go to the institution that issued the certificate and have them copy it, stamp it with the institutions stamp and apply a signature that "it is a true copy". You can go to a Notary Public as the last resort...for example if you went to school in another country and can't go back to that institution to get it certified...you can have a Notary public attest that it's a true copy... but as I said let this be last resort. I also urge you to ask these questions on the main page for a quicker response. The page is in the listing calle "Quebec Applicants Let's Share Our Experience"
