I guess call CIC is the fastest way , then eCase and last one letter.
there is a delay for CIC website to be uploaded while CIC call centre is connected to the updated system.
You consider yourself lucky if it's only 10 minutes lol , but sometimes it's worth it , in my case i called call center in the same day they mailed out a letter to me , so i found out about it before Ecase was updated like 4 days , the actual letter arrived like a week later.
