Lost or Stolen Device — Quick Reference Guide
Immediate steps, checklists, and reporting deadlines for Canadian organizations responding to a lost or stolen device under PIPEDA, Alberta PIPA, and BC PIPA.
Typical verdict
HIGH — unless confirmed encryption and verified no access
Reporting deadline
As soon as feasible after RROSH is determined — begin assessing immediately, do not wait for device recovery
Documents you will need
- → Internal Incident Record (always required)
- → OPC PIPEDA Breach Report (if PIPEDA RROSH triggered)
- → OIPC Alberta Notification Form (if AB PIPA applies)
- → OIPC BC Notification (if BC PIPA applies)
- → Individual Notification Letter
- → AB PIPA Individual Notice s.19.1 (if AB PIPA individual notification required)
Do not
- ✕ Assume 'we require encryption' means this device was encrypted — confirm through MDM
- ✕ Treat device recovery as resolution — verify data was not accessed
- ✕ Wait for the device to turn up before beginning your RROSH assessment
- ✕ Revoke the device from MDM without also revoking cached credentials (email, VPN, SSO)
First 30 minutes
- Trigger a remote wipe or remote lock through your MDM platform (Intune, Jamf, etc.) — record the timestamp and MDM confirmation
- Revoke VPN access, corporate email, and SSO sessions associated with the device
- Remove the device from your MDM enrollment or revoke its management certificate
- Designate one person as incident lead — all communications and decisions route through them
- If the device was stolen: file a police report promptly — document the report number
- If the device was lost in a public place: notify the location (hotel, transit authority, etc.) and request it be held — document this
Within 24 hours
- Confirm encryption status: was full-disk encryption (BitLocker, FileVault) active on the device at the time of loss? Can your MDM confirm compliance?
- Confirm whether a remote wipe completed — check MDM logs for confirmation the wipe executed before the device connected to any network
- Identify what personal information was on the device:
- Employee records, contact details
- Client or customer information
- Financial or banking data
- Health or medical information
- SINs or government-issued ID numbers
- Passwords, credentials, or authentication tokens
- Locally cached email (which may contain any of the above)
- Identify which provinces the affected individuals are in — this determines whether AB PIPA and/or BC PIPA apply in addition to PIPEDA
- Confirm whether any credentials cached on the device remain valid — revoke any that do
- Run your ClearBreach assessment — do not wait for the device to be found
Within 72 hours
- Complete your RROSH assessment in ClearBreach and review your verdict
- If PIPEDA RROSH threshold is met: file OPC Breach Report as soon as feasible — do not delay for device recovery or further investigation
- If Alberta PIPA applies and RROSH is met: notify OIPC Alberta (breachnotice@oipc.ab.ca) and affected individuals simultaneously
- If BC PIPA applies and RROSH is met: notify the OIPC BC through their official breach notification process and notify affected individuals
- Send individual notifications directly to affected individuals — do not substitute a website notice for direct notification
- Begin populating your Internal Incident Record with all actions taken, timestamps, and decisions made
Ongoing — until resolution
- If the device is recovered: obtain forensic verification or MDM log confirmation that data was not accessed — document the finding
- If forensic review confirms no access: reassess RROSH and update your regulator submission if the verdict changes materially
- Monitor connected accounts (email, cloud storage, VPN) for unauthorized access in the days and weeks following the incident
- Update your Internal Incident Record as new information becomes available
- Retain all records for 24 months minimum from the date the breach was discovered
- Review your device encryption and MDM enforcement policy — document any gaps identified and remediation steps taken
Alberta PIPA — specific steps
- Notify OIPC Alberta and affected individuals simultaneously — simultaneous filing triggers the streamlined review process and a private closing letter
- Complete the official OIPC Alberta Notification Form — do not substitute an informal letter
- Attach the AB PIPA Individual Notice (s.19.1) to your OIPC Alberta submission (Section D)
- Submit by email to breachnotice@oipc.ab.ca
BC PIPA — specific steps
- BC PIPA applies if any affected individuals are BC residents — applies regardless of where your organization is based
- Notify the OIPC BC through their official breach notification process (oipc.bc.ca)
- Notify affected BC residents directly — do not substitute a general public notice for direct notification
- File with the OIPC BC and notify affected individuals as soon as feasible after your RROSH determination
MSPs — if managing this for a client
- Execute the MDM remote wipe immediately — document timestamp and MDM confirmation
- Revoke device credentials from any systems you manage that the device had access to
- Confirm with the client in writing who leads regulatory notification before acting on their behalf
- Run a ClearBreach assessment under your MSP account for the affected client organization
- Document all client communications with timestamps
