Takes a little over 3 months. Probably won't be until early January till you see your application on eCAS.How long does it typically take from the day of mailing to "We received your application..."? I realize there are/have been recent Canada Post strikes...
I mailed my renewal in on September 17, and I'm unable to see any application found in the "Client Application Status" website:
https://www.canada.ca/en/immigration-refugees-citizenship/services/application/check-status.html
Am I missing something here?
