Public Wi-Fi: Convenience or Risk?

The Double-Edged Sword

Public Wi-Fi is everywhere — airports, cafés, libraries, buses — and it feels like a small miracle of modern life. But that “free” connection often comes with hidden costs. Without proper safeguards, using public Wi-Fi can expose your passwords, banking info, or personal messages to anyone with the know-how to snoop.

The Risks

  • Unencrypted networks: Some hotspots don’t encrypt traffic at all, leaving data visible.
  • Fake hotspots: Scammers set up look-alike networks (“CoffeeShop_WiFi”) to harvest logins.
  • Man-in-the-middle attacks: Hackers intercept traffic between you and the website you’re visiting.
  • Automatic connections: Phones often reconnect to familiar names like “Free Wi-Fi,” even if it’s malicious.
  • Data harvesting: Even legitimate providers may collect browsing data for marketing.

Canadian Context

  • Transit & municipal Wi-Fi: Growing across cities, but not all systems use strong encryption.
  • Tourism & travel: Canadians abroad often rely on unsecured hotel or café networks.
  • Youth and students: Heavy reliance on free Wi-Fi makes them particularly vulnerable.
  • Remote work: Many Canadians now handle sensitive work data in public spaces.

The Challenges

  • False sense of security: People assume a password-protected network is automatically safe.
  • Inconvenience: VPNs, mobile hotspots, and data plans cost money or take extra effort.
  • Awareness gap: Few users realize how easy it is to create a rogue hotspot.

The Opportunities

  • Safer defaults: Encourage providers to adopt stronger encryption (WPA3, HTTPS everywhere).
  • Practical habits: Use VPNs, turn off auto-connect, and avoid logging into sensitive accounts.
  • Public education: Libraries, schools, and community centres can teach Wi-Fi safety as part of digital literacy.
  • Backup options: Promote affordable mobile data alternatives for vulnerable populations.

The Bigger Picture

Public Wi-Fi highlights a larger tension: we’ve built infrastructure for connectivity, but not always for security. Access without protection can widen the digital divide rather than close it.

The Question

If connectivity is now a basic need, should safe and secure Wi-Fi be treated as civic infrastructure in Canada — not just a convenience?
