Its still other than Canada as per instructions below. I believe they ask for it if its required as per many posts on it earlier.

As read in the Document Checklist file to be sent with the application:
"Police Certificates and Clearances
You must get a police certificate from each country or territory where you have lived for six or more months in a row since the age of 18. You are strongly encouraged to submit your police certificates with your application to the CIO. If you are unable to obtain all the necessary police certificates, you may still send your application to the CIO without them. However, we strongly recommend that you take steps to obtain your police certificates now to avoid future delays. You must be ready to submit them when requested by an officer.
Note: Police certificates are generally considered to be valid for one year from date of issue; therefore depending on the processing time of your application, you may be requested to submit new certificates."
It's pretty straightforward. If it's been over a year since you EMITTED your police certificates, then yes, you must send new ones. However, if say in my case I got mine EMITTED Feb 2015 from my home country and sent them as originals WITH a true certified copy translated in English with my application in May 2015, then it means I don't have to send new ones.
If someone didn't send the police certificates with the original application, the reminder email serves that purpose: to remind the applicant police certificates need to be sent before finalizing processing.
Hope this clarifies any doubts.
