Yes. Ontario municipalities face cybersecurity obligations through the Ontario CSF and, in some cases, through their designation as critical infrastructure. Municipal councils are increasingly directing IT departments to reach defined CSF maturity levels. ThreeShield has delivered assessments for public-sector clients and understands the constraints of municipal IT environments.
Closely. The Ontario CSF aligns with NIST CSF and with the Canadian Centre for Cyber Security's baseline controls. Bill C-8 (CCSPA) may also impose obligations on Ontario entities operating in federally regulated critical infrastructure sectors. ThreeShield maps all applicable frameworks in one engagement.
ThreeShield's CISSP/CISA team delivers Ontario CSF maturity assessments with clear, prioritized remediation roadmaps.
