I got news of me being accepted as a sponsor on May 20th and we began our application April 17th. They began processing May 8th. I had a very simple application I am sponsoring my spouse from the US, my financials couldn't even be considered because I am on disability and they cannot discriminate. I also was born a Canadian Citizen, we were married in Canada, no criminal record, so my end was very easy for them to process. If you have a lot for them to look through I could see it taking a bit longer but over all I was happy with how quickly I was accepted as a sponsor. I forgot to add that I had not received this in the mail until the 29th so it took a long time to arrive but May 20th is the official acceptance date, so tack on a week for arrival.
