Since you are in Toronto, call 1-888-242-2100 between 8 am and 4 pm ET. If the lines are too busy, they might not put you in the queue to talk to an agent.
If you do enter the queue, you will wait about 27 mins on an average before getting connected to an agent (you do have the option to request call back).
When connected - just request the status of your application. They will ask you your application number, name, address, etc. You can ask specific questions (example) - status of eligibility, status of criminality, security, etc.
Also, you dont need to know your VO.
