The City of Markham's Access and Privacy office together with Information Technology Services typically handle cybersecurity incidents affecting municipal systems. Where personal information is involved, provincial rules under the Municipal Freedom of Information and Protection of Privacy Act (MFIPPA) apply; see the statute for legal duties and scope Municipal Freedom of Information and Protection of Privacy Act[1].

Immediate actions to take

  • Document timestamps, user accounts, IP addresses and steps taken; preserve logs and images as evidence.
  • Notify City of Markham IT/Access & Privacy staff as instructed by municipal incident response policies.
  • Begin an internal timeline of the event and notifications to support any statutory reporting.
Contact the municipal privacy or IT office immediately to avoid loss of evidence.

Penalties & Enforcement

Legal and administrative consequences for cybersecurity breaches depend on whether duties under MFIPPA or other statutes were contravened and on the facts of the incident. Specific monetary fines for public institutions are not set out on the MFIPPA statute page; penalties and remedies available to the Information and Privacy Commissioner are described in provincial guidance and orders IPC guidance on responding to breaches[2].
