Dear CSIS
Since you are monitoring my smartphone and my computer via metadata and email as part of a Canadian security act, it's your obligation to keep me safe from harm.
I know you know where I live. The purpose of Big Brother is not just to spy on me to protect national security; it's also to protect each citizen who submits to such scrutiny from harm.
This is what Section 7 of the Canadian Charter of Rights and Freedoms legally obligates the Government of Canada to do: the right to life, liberty, and security of the person. As part of the Canadian government, that too is part of your mandate.
That's what we pay our taxes for.
