I'd try and give them a call to see what's going on. If you're in Canada call +1 888 242 2100, if you're outside of Canada try +613 944 4000.
I called them and they updated me relatively quickly. Thursday & Friday are the best days to call.
If you can't get through, you can contact them via the web form:

- Choose Yes for the "Have you submitted an application for" question.
- Choose No for the "Is your application being processed outside Canda?" question.

- In the type of application, choose sponsorship, then spousal in the box below.
- Fill all of the details in. However, in the application number box, put your receipt number in.
- For your enquiry, ask them if they can update you on your application as you've now been waiting nearly 4 months for AOR.
You'll get a reply within 7 days and they will provide an update.
