Detention facilities are government-run centers that hold non-citizens who are awaiting immigration proceedings or removal from a country. These facilities serve as temporary housing for people who authorities believe may not appear for court dates or pose public safety risks.
Key Types of Detention Facilities:
Major Countries Operating Detention Systems:
The scale of immigration detention has grown dramatically worldwide. In Canada alone, detention numbers jumped from 4,248 people in 2016-2017 to 6,609 the following year - a 56% increase in just one year.
These facilities range from purpose-built immigration centers to repurposed county jails. Conditions vary widely, with some offering basic amenities while others face criticism for overcrowding, inadequate medical care, and prolonged detention periods.
The human cost is significant. Between 2003-2008, about 104 individuals died in U.S. Immigration and Customs Enforcement custody, with medical neglect potentially contributing to 30 of those deaths.
I'm Tim Burd, and through my legal services company Justice Hero, I've helped connect people with attorneys who handle cases involving detention facilities and immigration rights violations. My experience working with affected families has shown me how crucial it is to understand these complex systems and the rights people have within them.

Essential detention facilities terms:
Immigration detention serves a specific purpose within national immigration systems. At its core, it's the policy of holding individuals suspected of visa violations, unauthorized arrival, or those pending deportation until authorities make a decision about their status.
The legal framework governing detention facilities varies by country but generally stems from immigration laws designed to ensure people appear for court proceedings and protect public safety. In Canada, the Immigration and Refugee Protection Act (IRPA) provides the foundation, while the U.S. operates under the Immigration and Nationality Act.
Primary purposes of immigration detention include:
The legal standards draw from international frameworks like the Refugee Convention, which establishes that detention should be a last resort and used only when necessary and proportionate.
People find themselves in detention facilities for various reasons, most commonly:
Inadmissibility issues - This includes individuals with criminal convictions, health concerns, or security risks. Even minor criminal offenses can trigger detention under mandatory detention provisions.
Visa overstays - People who remain in a country beyond their authorized stay period may be detained when finded by immigration authorities.
Identity problems - When authorities cannot verify someone's identity or nationality, they may be held until proper documentation is obtained. This often affects asylum seekers who arrive without documents.
Security certificates - In extreme cases, individuals suspected of terrorism or serious security threats may be detained under special security provisions.
Our research shows that factors determining detention include criminal history, compliance with previous immigration requirements, community ties, cooperation with identity establishment, and links to organized crime.
Detention facilities fall into distinct categories based on their primary function:
Administrative detention facilities are purpose-built for immigration cases. These include Canada's Immigration Holding Centres (IHCs) and dedicated ICE facilities in the U.S. They're designed specifically for civil immigration detention rather than criminal punishment.
Criminal detention involves housing immigration detainees in county jails, provincial correctional facilities, or federal prisons. This happens when dedicated immigration facilities are full or when detainees are considered high-risk.
Ad hoc facilities are temporary or converted spaces used during emergencies or capacity overflows. These might include converted hotels or military bases.
Unknown classification refers to facilities where the exact nature or conditions aren't clearly documented - a concerning gap in transparency.
The distinction matters because conditions, rights, and treatment standards can vary significantly between these facility types.
The worldwide network of detention facilities spans continents and involves millions of people annually. Each country has developed its own approach, creating a patchwork of systems with varying standards and practices.
Canada operates three main Immigration Holding Centres:
United States runs the largest system with over 200 facilities housing approximately 31,000 people daily. These range from dedicated ICE facilities to contracted county jails and private prisons.
Australia's system includes both onshore and offshore facilities, with the latter located on remote islands like Nauru and Manus Island.
United Kingdom operates Immigration Removal Centres (IRCs) across England and Scotland, with facilities like Yarl's Wood and Brook House.
| Country | Daily Population | Average Stay | Dedicated Facilities |
|---|---|---|---|
| Canada | 300-400 | 13.9 days | 3 IHCs |
| United States | 31,000+ | Variable | 200+ facilities |
| Australia | 1,500+ | Variable | Multiple onshore/offshore |
| United Kingdom | 2,000+ | Variable | 10 IRCs |
The distinction between administrative and criminal detention facilities is crucial for understanding detainee rights and conditions.
Administrative facilities are specifically designed for immigration detention. They typically offer:
Criminal facilities house immigration detainees alongside criminal offenders. This creates challenges:
In Canada, about 32% of immigration detainees are held in provincial jails, while 68% are in dedicated IHCs. This represents an improvement from previous years when more detainees were held in criminal facilities.
Monitoring bodies like the Canadian Red Cross have noted significant differences in conditions between facility types, generally favoring purpose-built immigration centers over criminal facilities.
Canada's system centers on three Immigration Holding Centres near major airports. The Laval IHC in Quebec can hold up to 109 people, while Toronto's facility accommodates 183. The newest facility in Surrey, British Columbia, houses up to 70 detainees.
Canada's National Immigration Detention Framework emphasizes using detention as a last resort and aligning with international standards. The country has no statutory time limit on detention, but regular reviews occur - CBSA officers must review within 48 hours, and the Immigration and Refugee Board reviews within seven days and every 30 days thereafter.
United States operates the world's largest immigration detention system. ICE's Enforcement and Removal Operations manages facilities from coast to coast. The system includes:
The U.S. made detention mandatory in 1996 following the Oklahoma City bombing, significantly expanding the population subject to detention.
United Kingdom's Immigration Removal Centres house people awaiting deportation or appeal outcomes. Notable facilities include Yarl's Wood (for women and families) and Brook House near Gatwick Airport.
Australia pioneered mandatory detention in 1992 for all non-citizens arriving without visas. The system includes both onshore facilities and controversial offshore processing centers on Pacific islands.
The Safe Third Country Agreement between the U.S. and Canada affects detention patterns, as asylum seekers may be detained while authorities determine which country should process their claims.

Living conditions in detention facilities vary dramatically depending on the facility type, country, and local standards. While some modern facilities offer basic amenities, others face persistent criticism for overcrowding, inadequate medical care, and prolonged detention periods.
Common conditions issues include:
Overcrowding - Many facilities operate above capacity, leading to cramped living conditions and strained resources.
Medical care gaps - Access to healthcare varies widely. Our research revealed that medical neglect may have contributed to 30 deaths in U.S. ICE custody between 2003-2008.
Mental health concerns - Prolonged detention can exacerbate mental health issues, with limited access to appropriate treatment.
Food quality - Detainees often report poor nutrition and culturally inappropriate meals.
Recreation and programming - Limited activities and educational programs can make detention particularly difficult for long-term detainees.
The Canadian Red Cross monitors conditions in Canada's IHCs and has noted improvements in recent years, though concerns remain about the use of provincial jails for immigration detention.
Despite being held in detention facilities, individuals retain important legal rights:
Due process rights - Detainees must be informed of the reasons for their detention and have the right to challenge it through review hearings.
Legal representation - Access to lawyers is fundamental, though the quality and availability of legal aid varies by jurisdiction.
Consular access - Foreign nationals have the right to contact their home country's consular officials.
Interpretation services - Detainees must have access to interpreters for legal proceedings and important communications.
Medical care - Facilities are constitutionally required to provide necessary medical treatment.
Religious practice - Reasonable accommodation for religious observance and dietary requirements.
Communication rights - Ability to contact family members and legal representatives, though this may be monitored.
Habeas corpus - The right to challenge the legality of detention in court.
In Canada, the Charter of Rights and Freedoms provides additional protections, while U.S. detainees can invoke constitutional protections against cruel and unusual punishment.
Detention facilities must provide special protections for vulnerable populations, though implementation varies significantly.
Children in detention represent one of the most concerning aspects of immigration detention. In Canada, 138 minors were detained between April 2019 and March 2020, mostly with a detained parent. The principle of "best interests of the child" should guide all decisions, but enforcement is inconsistent.
Pregnant women require specialized medical care and accommodations. Many facilities lack adequate prenatal care, and the stress of detention can negatively impact pregnancy outcomes.
People with mental health conditions face particular challenges. The 2014 suicide of Lucía Dominga Vega Jiménez at Vancouver Airport highlighted gaps in mental health training and support.
Elderly detainees may have complex medical needs that facilities struggle to address adequately.
LGBTQ+ individuals face heightened risks of discrimination and violence, particularly in facilities that mix immigration and criminal populations.
Trafficking victims should receive protection rather than detention, but identification and proper treatment remain inconsistent.
The UN Joint Comment on children in immigration detention emphasizes that child detention should be prohibited, not merely used as a last resort.

Recognition of detention facilities' limitations has sparked development of alternatives and reform efforts worldwide. These changes aim to address human rights concerns while maintaining immigration enforcement.
Alternatives to Detention (ATDs) have gained traction as more humane and cost-effective approaches:
Community case management - Providing support services to help individuals steer immigration proceedings while living in the community.
Electronic monitoring - Using GPS or radio frequency devices to track individuals' locations.
Reporting conditions - Requiring regular check-ins with immigration authorities.
Bond arrangements - Allowing release upon payment of a financial guarantee.
Residential facilities - Less restrictive housing options that provide support while maintaining some oversight.
Canada has integrated ATDs with the UNHCR Global Detention Strategy, emphasizing non-custodial alternatives. During COVID-19, Canada dramatically reduced detention numbers from 353 on March 17, 2020, to 147 by April 19, 2020, largely through expanded use of alternatives.
Recent reforms have focused on:
Successful ATD programs share common characteristics:
The Toronto Bail Program helps migrants secure release by posting bond and providing case management services. This program demonstrates how community support can effectively ensure court appearances while allowing people to maintain family and employment ties.
Community Case Management and Supervision programs align support services with individual needs, addressing underlying issues that might affect compliance with immigration requirements.
Electronic monitoring pilot programs in Canada's Prairie, GTA, and Quebec regions use GPS and radio frequency technology to track participants while allowing them to remain in the community.
Reporting conditions require regular check-ins with immigration authorities, providing oversight without the costs and trauma of detention.
What works:
What doesn't work:
Research shows that well-designed ATD programs achieve compliance rates of 80-90% while costing significantly less than detention.
Oversight of detention facilities involves multiple actors with varying levels of access and authority:
The Canadian Red Cross monitors conditions in Canada's IHCs under a formal agreement with the CBSA. Their reports and recommendations have led to improvements in facility conditions and policies.
Non-governmental organizations play crucial roles in monitoring, advocacy, and service provision. Organizations like the International Detention Coalition work globally to improve detention conditions and promote alternatives.
Parliamentary committees conduct reviews and investigations, though their effectiveness depends on political will and resources.
The Committee for the Prevention of Torture (CPT) visits facilities in Council of Europe member states, providing independent assessment of conditions.
Ombudsman offices in various countries investigate complaints and systemic issues.
Courts provide oversight through habeas corpus proceedings and constitutional challenges.
However, significant gaps remain. Canada has not ratified the Optional Protocol to the Convention against Torture (OPCAT), which would establish independent monitoring mechanisms. Many facilities lack regular independent oversight, and transparency remains limited.
The average length of stay in detention facilities varies significantly by country and individual circumstances. In Canada, the average detention period decreased from 26.3 days in fiscal year 2014-15 to 13.9 days in 2019-20, reflecting policy reforms and improved case processing.
However, some individuals face much longer detention periods. Michael Mvogo was detained for nearly nine years before repatriation in 2015, highlighting the reality of indefinite detention in systems without statutory time limits.
Factors affecting detention length include:
Detention facilities are not the same as prisons, though the distinction can be blurred in practice. Immigration detention is technically civil rather than criminal, meaning it's not intended as punishment but as an administrative measure.
Key differences:
However, when immigration detainees are housed in criminal facilities, the practical differences may be minimal. About 32% of Canadian immigration detainees are held in provincial jails alongside criminal offenders.
Yes, detainees in detention facilities have rights to legal representation and family contact, though the extent and quality of access varies.
Legal access includes:
Family contact typically involves:
However, practical barriers can limit these rights:
The quality of access often depends on facility type, with dedicated immigration centers generally providing better access than criminal facilities.
Understanding detention facilities is crucial for anyone navigating immigration systems or advocating for detained individuals. These facilities represent a complex intersection of immigration law, human rights, and public policy that affects hundreds of thousands of people worldwide.
At Justice Hero, we believe knowledge is power. By understanding how these systems work, what rights people have, and what alternatives exist, we can better advocate for fair treatment and humane policies. Whether you're seeking information for yourself, a family member, or as part of advocacy work, this knowledge helps level the playing field.
The landscape of immigration detention continues to evolve, with growing recognition that detention should be used sparingly and with robust safeguards. Alternatives to detention show promise, and oversight mechanisms are slowly improving, though significant challenges remain.
Key takeaways:
If you or someone you know is affected by immigration detention, rights exist even within these systems. Legal representation, consular access, and humane treatment are not privileges but rights that must be protected and enforced.
