Short answer: you don’t need to rush, but you should start paying attention.

**What governments are doing**

– **Canada:** In June 2025, the Canadian Centre for Cyber Security published a roadmap
for migrating Government of Canada non-classified systems to post-quantum cryptography.
Departments were to submit initial migration plans by April 2026, complete high-
priority systems by the end of 2031, and finish all remaining systems by 2035.

– **United States and United Kingdom:** Similar roadmaps point to the early-to-mid
2030s for completing transitions.

– **Financial sector:** International regulators have called for coordinated transition
planning.

The Cyber Centre notes that not all existing systems can be retrofitted. Some will
need to be replaced.

**Why it matters to private businesses**

– **Suppliers to government** may face contract requirements for quantum-safe systems
over time

– **Customers in finance and healthcare** may begin asking about your plans

– **Your vendors** will roll out PQC in browsers, operating systems, VPNs, and cloud
platforms, usually through normal updates

– **Equipment bought today** may still be in use in 2035. Choose vendors that commit
to updates.

**A sensible business approach**

**Now:**

– Make an inventory of where you use encryption (VPNs, certificates, applications,
hardware)

– Identify data that must remain confidential long-term

– Ask key vendors for their PQC timelines

**Over the next few years:**

– Keep systems and firmware current

– Prefer vendors with a clear PQC roadmap in purchasing decisions

– Retire unsupported systems

**Later:**

– Test and adopt PQC features as they appear in your platforms

**What not to do**

– Don’t buy “quantum-proof” products from unproven vendors

– Don’t build your own encryption

– Don’t let this distract from basics like MFA and patching, which prevent far more
attacks today
