This is a public forum try asking them directly, I would recommend an email and they reply usually same day if you send it early enough but with in 24 hours for sure. Just click contact us then the e-mail option.
I do believe the 18 month rule applies meaning if there is a bill or usage within the last 18 months, it can be viewed. In the event of a court order, the courts or police will have the proper legal channels to follow to contact Koodo for such a request. You do not have to do the leg work yourself
EDIT: That is assuming the phone has already received them
