@ Leo12,
My understanding is that they only show average processing times when the VO has processed more than 10 applications (in that category) for the period.
Once the VO does not process more than 10 applications it will show - .
My case is through Port of Spain visa office and it has showed that for the past 4 years. When I checked the Open Data reports it showed that they only processed an average of 6 cases per year in my category.
The following is quoted from CIC's website:
Notes
•You can view your application status online.
•If it has been longer than the time shown above since you applied and your visa office has not contacted you, you may wish to contact the visa office that is processing your application by e-mail, letter or fax. The Call Centre does not have information about applications processed outside Canada.
•(-) indicates that not enough data are available. Processing times are shown only where an office has finalized 10 or more cases in the past 12 months.
