for Inland currently it is taking more than month to receive portal invite, after portal invite you will receive the ecopr doc on portal. In my case I have been waiting from oct17
for inland applicant you first get the email for declaration, then IRCC send credentials for portal to apply PR card. After uploading photo to it , few days later COPR become available on portal to download.
Lately they are so slow to issuing the email. there are at least 20-22 people waiting for email after decision made from last 1 to 6 week. so there is no time frame.
