I was able to log in to ecas this morning, 3 days after receiving email of sponsorship approval. Everything in the "Sponsorship Application Status" is accurate; regarding "Permanent Residence Application Status", besides the date the application was received (the same date CPC-M got it), it also states that "medical results have been received." I guess we can safely assume that CPC-M does have access to all info received by VO abroad (e.g., medical results), and thus able to link them to the original file. Just a thought.
