In 2013, a 29-year-old intelligence contractor walked away from his life in the United States carrying some of the most closely guarded secrets in American intelligence.
His name was Edward Snowden.
What he revealed would ignite a worldwide debate about government surveillance, personal privacy, and just how much information intelligence agencies could collect about ordinary people.
The leaked documents exposed secret surveillance programs capable of collecting enormous amounts of communications data. They also revealed intelligence-gathering capabilities far more extensive than many people had realized.
Snowden became one of the world’s most controversial whistleblowers. Supporters regarded him as someone who exposed serious threats to privacy. Critics argued that his disclosures compromised national security and revealed sensitive intelligence methods.
More than a decade later, the technology used to communicate has changed dramatically. Smartphones are everywhere, encrypted messaging has become mainstream, and artificial intelligence has introduced new ways to analyze enormous amounts of information.
But one question remains.
After everything Snowden exposed, are governments still watching and listening?
The Man Who Exposed a Secret Surveillance System
Edward Snowden was working as a contractor for the National Security Agency (NSA), the American intelligence organization responsible for signals intelligence and cybersecurity, when he began collecting classified documents about its surveillance activities.
In June 2013, journalists at The Guardian and The Washington Post began publishing reports based on those documents.
The revelations were extraordinary.
One of the first stories described a secret court order requiring Verizon Business Network Services to provide the NSA with records of telephone calls on an ongoing basis.
These records included information such as the numbers involved, when calls occurred, and how long they lasted.
They did not, under that particular order, include the actual audio of conversations.
That distinction mattered, but the privacy implications were still significant. Even without listening to a call, records of who communicates with whom can reveal relationships, routines, and patterns of behaviour.
Other disclosures described surveillance involving major internet services, international communications networks, and cooperation between intelligence agencies.
The public was suddenly confronted with a disturbing possibility: vast amounts of personal communications information could be collected without most people knowing.
What Exactly Did Snowden Reveal?
The Snowden documents exposed multiple surveillance activities, but three became particularly important to the public debate.
1. Bulk telephone metadata collection
The NSA had operated a program collecting large volumes of domestic telephone metadata under Section 215 of the USA PATRIOT Act.
The information could reveal communications patterns, even though the program did not involve recording everyone’s conversations.
2. PRISM and internet communications
Another disclosure concerned PRISM, a surveillance program operating under Section 702 of the Foreign Intelligence Surveillance Act.
PRISM enabled the government to obtain certain communications from American technology providers under legally authorized procedures targeting non-U.S. persons reasonably believed to be outside the United States.
Early reporting generated confusion about whether intelligence agencies had unrestricted access to company servers. The program did not establish that the NSA could simply open any person’s account whenever it wanted.
Nevertheless, the disclosures demonstrated that intelligence agencies could obtain significant amounts of digital communications through mechanisms largely unfamiliar to the public.
3. Surveillance of international communications
The leaked documents also revealed intelligence collection involving international telecommunications infrastructure, including programs associated with the interception of communications moving across major networks.
These disclosures raised questions not only about American privacy protections but also about the rights of people living outside the United States.
The central issue was no longer whether governments had the technical ability to conduct extensive surveillance.
It was how far that surveillance should be allowed to go.
What Happened to Edward Snowden?
After meeting journalists in Hong Kong, Snowden travelled to Russia, where he became stranded after American authorities revoked his passport.
The United States charged him under the Espionage Act and with theft of government property.
Snowden maintained that he disclosed the documents to expose surveillance practices that the public deserved to know about.
The American government argued that he unlawfully disclosed classified information and damaged national security.
He eventually received asylum in Russia and later obtained Russian citizenship in 2022.
His case continues to illustrate a difficult conflict between two principles: the public’s interest in learning about government activities and the government’s responsibility to protect classified intelligence.
But while Snowden’s personal story captured international attention, the surveillance systems he exposed were the subject of changes that would have much broader consequences.
Did Snowden’s Revelations Actually Change Anything?
Yes. Some of the most controversial surveillance practices he exposed were subsequently restricted or discontinued.
In 2015, the United States passed the USA FREEDOM Act, which ended the NSA’s bulk telephone metadata collection program under Section 215.
Instead of allowing the government to collect enormous quantities of telephone records under that program, the legislation established a more targeted process involving records retained by telecommunications providers.
The NSA later suspended that replacement call-detail-records program, and the relevant legal authority expired in 2020.
But ending one program did not mean ending government surveillance.
Other intelligence collection authorities continued, including Section 702 of the Foreign Intelligence Surveillance Act.
And that brings us to the question at the centre of Snowden’s legacy.
Are Governments Still Listening Today?
Yes. Governments still conduct electronic surveillance, including the interception of communications. But that does not mean they are secretly recording every person’s phone calls or monitoring every private conversation.
The distinction is important.
Intelligence agencies continue to use electronic surveillance to investigate foreign intelligence threats, terrorism, espionage, and other national security concerns.
One of the most closely scrutinized American surveillance authorities is Section 702 of the Foreign Intelligence Surveillance Act.
Under this framework, intelligence agencies can target non-U.S. persons reasonably believed to be outside the United States to acquire foreign intelligence information.
The government does not need to obtain an individual court order for each foreign target. Instead, surveillance operates under procedures reviewed by the Foreign Intelligence Surveillance Court.
A complication arises when an American communicates with someone being monitored overseas.
That American’s communications may be collected incidentally, even though the American was not the surveillance target.
Privacy advocates have also raised concerns about intelligence agencies searching previously collected communications for information about Americans without first obtaining an individualized warrant.
What Changed in 2026?
Section 702’s statutory authority expired on June 12, 2026, after Congress failed to enact another extension before the deadline.
But the expiration did not immediately end surveillance under the program.
Existing surveillance certifications approved by the Foreign Intelligence Surveillance Court can remain effective until March 17, 2027.
That means intelligence collection authorized under those certifications can continue despite the statutory expiration.
The situation illustrates why ending a particular surveillance law does not necessarily mean that surveillance stops overnight.
Other intelligence authorities also exist, and not every government surveillance operation depends on Section 702.
Can the Government Actually Listen to Your Phone Calls?
Technically, governments possess capabilities to intercept certain telephone and internet communications.
But the circumstances under which those capabilities can legally be used depend on the country, the type of investigation, the surveillance authority, and the people involved.
There is also an important difference between collecting metadata and intercepting communications content.
Metadata can include information about when a call occurred, how long it lasted, and which numbers were involved.
Communications content refers to the actual words spoken, messages exchanged, or other information transmitted.
Snowden’s disclosures showed why both categories can raise privacy concerns.
A government might learn a great deal about someone’s relationships and activities from communications records without hearing a single conversation.
But access to metadata does not automatically mean access to the content of a call.
Similarly, the existence of powerful surveillance technology is not evidence that every person is being individually monitored.
What About WhatsApp, Signal, and Encrypted Messages?
Modern encryption has changed the surveillance landscape considerably.
End-to-end encryption is designed to ensure that only the communicating endpoints can read the contents of protected messages.
For example, Signal uses end-to-end encryption for its messages and calls, while WhatsApp provides end-to-end encryption for personal messages and calls.
When properly implemented, this protection prevents a network operator or someone intercepting the connection from simply reading the encrypted conversation.
However, encryption is not the same as complete anonymity.
An intelligence agency or attacker might obtain communications through other methods, including access to an unlocked device, compromised software, or information stored outside an encrypted conversation.
Different services also collect and retain different types of account information and metadata.
A secure messaging application can substantially protect message contents while still leaving other information exposed.
This is one reason digital privacy experts emphasize that security depends on more than choosing an encrypted app.
What About Canada? Could Canadians Be Monitored Too?
The Snowden disclosures were not exclusively an American issue.
Canada is a member of the Five Eyes intelligence partnership alongside the United States, the United Kingdom, Australia, and New Zealand.
The partnership facilitates intelligence cooperation among the five countries.
Canada also operates its own signals intelligence agency, the Communications Security Establishment (CSE).
Under Canadian law, CSE has foreign intelligence and cybersecurity responsibilities, subject to statutory restrictions, authorization requirements, and oversight.
Its foreign intelligence activities cannot be directed at Canadians anywhere in the world or at anyone located in Canada.
However, Canadian communications can raise privacy issues when they are incidentally acquired during authorized foreign intelligence operations.
For example, information about a Canadian might be collected when CSE monitors a foreign intelligence target outside Canada.
The law recognizes that possibility and establishes requirements intended to protect Canadian privacy.
CSE’s activities are also subject to independent review and, for certain authorizations, approval by Canada’s Intelligence Commissioner.
For Canadians, the Snowden story is relevant because digital communications frequently cross international networks and involve companies headquartered in other countries.
A message sent from Canada may depend on foreign-owned infrastructure or services, even when both people involved live in Canada.
That does not mean foreign intelligence agencies automatically have lawful access to it.
It means the privacy implications of international communications cannot always be understood by looking at Canadian law alone.
Has Artificial Intelligence Made Surveillance More Powerful?
Artificial intelligence has introduced another dimension to the debate.
Modern computer systems can analyze enormous quantities of information, identify patterns, translate languages, and detect relationships between data points.
These capabilities can make certain intelligence analysis tasks faster and more scalable.
Consider the difference between manually examining thousands of communications records and using software to identify potentially relevant connections.
Automated analysis may help investigators identify patterns that would otherwise take much longer to discover.
But the existence of these capabilities does not establish that a government is using AI to monitor every citizen.
It also does not eliminate the legal requirements governing how information is collected.
The privacy concern is that increasingly sophisticated analytical tools may allow governments to extract more information from data they already possess.
Even when the underlying records remain unchanged, advances in analysis can alter what those records reveal.
That creates new questions about oversight, accuracy, accountability, and the potential for misuse.
Was Snowden a Hero or a Traitor?
More than a decade after the disclosures, Snowden remains a divisive figure.
Supporters argue that he exposed surveillance practices that the public had a right to understand.
They point to the ensuing legal challenges, government reviews, public debate, and reforms as evidence that the disclosures served an important public interest.
Critics maintain that Snowden violated his obligations to protect classified information and that publishing sensitive intelligence material harmed national security.
The controversy is not simply about whether privacy matters or whether intelligence agencies should exist.
It is about who should decide when government secrecy is justified, how intelligence activities should be supervised, and what options are available when someone believes a classified program is improper.
Snowden’s case also raises questions about whistleblower protections and the risks involved in disclosing national security information.
Those disagreements remain unresolved.
Yet regardless of how Snowden himself is judged, his disclosures helped bring surveillance practices previously hidden from public view into a global conversation.
So, Are They Still Listening?
Thirteen years after Snowden’s revelations, government surveillance has not disappeared.
Intelligence agencies still have technical capabilities to intercept communications, obtain information from service providers, and analyze communications data under applicable legal authorities.
Some programs exposed in 2013 were ended or substantially changed. Others continued under different rules, and newer technologies have introduced additional privacy challenges.
At the same time, stronger encryption has made many everyday communications more difficult to intercept and read.
The evidence does not support the sweeping claim that governments are listening to every conversation. Nor does it support the opposite claim that Snowden’s disclosures brought widespread electronic surveillance to an end.
The more important question may no longer be whether governments have the technology to monitor communications. It is who can be monitored, under what authority, and who ensures those powers are not abused.
Snowden exposed a surveillance system that much of the public knew little about.
More than a decade later, the debate he helped ignite is far from over.
