These bills, along with C-22 and C-9 constitute a total erosion in Canada’s basic liberties. They interlock into making Canada essentially unviable for those with choices on where to build.
You've likely seen the headlines from bills C-34, C-36, and C-22 in the media.
Each may sound reasonable on their own: protect kids online, modernize privacy, help police catch criminals.
But buried within is an emerging Digital Regulatory Superpower unlike anything Canadians have ever seen.
These bills hand one unelected commission power over what Canadians can say, what stays private, and who the state can watch.
As of today, the Federal Government is rushing to enact massive Internet Surveillance Reform into law without proper debate.

.@joswr1ght just announced a 720-page modern incident response book. 18 months in the making. The first comprehensive update to foundational IR frameworks since 2001. Released to the community for free. “Someone asked me, ‘Do you like writing?’ I say, ‘No, I like having written.’ That’s a different thing altogether. But I wrote this book because I kept seeing the same problems over and over again.” This is what giving back looks like.

Community contributions to tracking adversaries are underrated. Thank you for the blog post @eSentire - and for actually doing a PR/fork to assist in deobfuscation.

I’m excited to let you know that the talks from [un]prompted—the AI Security Practitioner Conference—are now live on YouTube.
No fluff, no hype—just real-world AI security from people actually doing the work.

Everyone talks AI copilots. We built something that actually thinks. 🧠
We deployed @AnthropicAI's Claude across our Atlas XDR Platform so it reasons like a senior analyst to achieve 43x speed, 95% accuracy.

This week is the biggest gathering of young builders... anywhere... with @socraticainfo hosting an ambitious symposium. A lot of VCs will have someone here in Waterloo.
Where are the GPs? You here too? If you want to see the talent that Canada might lose... you need to be here.
