Here is the number : 613-944-4000. Just listen to the options and press the appropriate number. They will ask for your application number, don't enter anything, just wait for it to ask three times and then they will connect you to an agent. Sometimes the call volume Is high and they will ask you to call again later, you just have to keep trying. When you get through to an agent, ask for the status of your application, and if you get it, nicely ask for your UCI. Some agents may tell you that they can't help you, just keep calling back. I had to call 3 times.
GOOD LUCK!!!!!
