AU CANADA, LES POLICIERS VONT UTILISER LES RÉSEAUX SOCIAUX POUR PRÉDIRE LES DISPARITIONS AVANT QU’ELLES NE SE PRODUISENT

Avec une base de données suffisante et une intelligence artificielle, il est parfois possible d'anticiper certains incidents. Certaines plateformes, comme Facebook, travaillent sur des algorithmes permettant de repérer les adolescents suicidaires et d'intervenir dans le cas où ils risquent de passer à l'acte. Au Canada, les forces de l'ordre vont utiliser des modèles prédictifs pour prédire les disparitions avant qu'elles n'aient lieu.

Selon un rapport du gouvernement, les modèles prédictifs seront basés sur des publications sur les réseaux sociaux, les dossiers de la police et les services sociaux. Les algorithmes se référeront à une dizaine de facteurs de risques communs, comme des antécédents de fugue ou de violence à la maison, afin d'identifier les personnes susceptibles de disparition.

L'initiative fait toutefois l'objet de nombre de critiques. Certains experts pensent que l'utilisation de modèles prédictifs à cette fin pourrait conduire à de faux positifs.

Le type d'informations à utiliser n'a pas été dévoilé

Le document a été publié le mois dernier par la RDDC (Defence Research and Development Canada), une agence rattachée au ministère de la Défense nationale. Selon le rapport, la conception des modèles prédictifs sera assurée par SPPAL (Saskatchewan Police Predictive Analytics Lab).

Ce laboratoire est le fruit d'un partenariat entre la police, le ministère provincial de la Justice et l'Université de la Saskatchewan.

La police canadienne utilise déjà les réseaux sociaux pour repérer des cas d'infraction, trouver des suspects et résoudre des enquêtes.

Toutefois, le rapport n'indique pas les types d'informations qui seront recueillies sur les médias sociaux.

Des risques de faux positifs

Tamir Israel est avocat à CIPPIC (Canadian Internet Policy and Public Interest Clinic). Il a reconnu que les modèles prédictifs de SPPAL pourraient être utilisés pour trier les cas suspects selon leur ordre de priorité. Il est en effet nécessaire de distinguer, par exemple, une éventuelle victime d'enlèvement d'une fugueuse habituelle. « Les forces de l'ordre seront invitées à s'appuyer sur les résultats du modèle prédictif » pour décider de la sérieuse prise en charge d'un cas de personne disparue », a-t-il déclaré à Motherbord.

Toutefois, il a souligné que ces modèles prédictifs sont souvent opaques dans leur fonctionnement, en s'appuyant sur des facteurs que les policiers eux-mêmes ne peuvent pas évaluer ou deviner. Il a noté que les informations sur les réseaux sociaux ne sont pas toujours fiables et augmentent les risques de faux positifs.

Il a également noté que cette méthode pourrait conduire à des résultats faussés lorsque les modèles sont appliqués à des groupes minoritaires. Il craint qu'ils ne fassent pas de différences entre les cultures.

« Nous savons que les modèles prédictifs sont loin d'être infaillibles dans des situations réelles et qu'il y aura des faux positifs », a-t-il rappelé. « Les conséquences d'une intervention basée sur un faux positif peuvent être très graves. »

  • How selecting the Lockheed Martin F-35 could impact Canada’s economy

    How selecting the Lockheed Martin F-35 could impact Canada’s economy

    Posted on August 12, 2020 by Chris Thatcher The Lockheed Martin F-35A Lightning II has long been considered the favourite to replace the Royal Canadian Air Force (RCAF) CF-188 Hornet. But in a competition now being contested in a weakened economy in which the government faces a ballooning deficit and an uncertain job market, how well each fighter jet scores on acquisition and sustainment costs and economic benefits to Canada – worth 40 per cent of the evaluation – could be almost as important as how well the aircraft meets the Air Force's capability requirements. The Joint Striker Fighter (JSF) has become the most expensive weapons program ever for the U.S. Department of Defense and could cost more than US$1 trillion over its 60-year lifespan, according to the New York Times. The Department of National Defence in 2013 estimated the full cost of procuring and operating the F-35A at US$45 billion over 30 years. Others have pegged the number far higher. Furthermore, under the rules of the JSF partnership agreement, to which Canada is a signatory, Lockheed Martin cannot offer traditional industrial and technological benefits (ITBs) to Canadian industry. If company officials are feeling at a disadvantage, they aren't admitting it. “We understand the rules, we understand the way the competition is structured and the requirements,” said Steve Callaghan, Lockheed Martin's vice-president of F-35 development and a former U.S. Navy F-18 squadron commander and Fighter Weapons School instructor. In an online briefing to media on Aug. 6, Callaghan shared the results of an economic impact assessment that suggested selection of the F-35 could impact GDP by almost $17 billion and generate more than 150,000 jobs over the life of the program. Lockheed Martin submitted its 7,000-page bid on July 31 to replace the RCAF's 94 legacy Hornets with 88 F-35A fighters. The proposal is one of three the federal government received at the deadline for a contract valued at up to $19 billion. Boeing's F/A-18E/F Super Hornet and Saab's Gripen E are also in the running. The government may begin negotiations with one or more of the compliant bidders once the initial evaluation is completed, likely by next spring. The final decision is expected in 2022 and first deliveries by 2025. As the RCAF and Public Services and procurement Canada now begin to evaluate the proposals, Lockheed Martin was keen to remind Canadians the F-35A is the only fifth-generation fighter in the competition. “It truly is a generation ahead of any other fighter in production and can be procured for about the same or less than the far less capable fourth-generation aircraft,” said Callaghan. Though the Joint Strike Fighter program was originally launched with the intent of developing a more cost-effective family of aircraft with a shared design and common systems, and high production volume to reduce procurement and sustainment costs, the ambitious program has struggled with high development costs and the final price tag. However, between the second Low Initial Production Rate (LRIP) in 2008 and LRIP 10 in 2016, the cost of an F-35A decreased by about 60 per cent. As Lockheed Martin ramps up to a production rate of about 141 aircraft per year for LRIP 14, its reached a per unit cost of about US$78 million. The aim now is to bring the cost per flight hour down under US$25,000 by 2025. “We are putting that same level of focus, that same level of rigour and innovation to reduce sustainment costs,” said Callaghan. “With ... every flight hour, the enterprise gets smarter, more mature, more effective, more on track to meet several critical performance and affordability targets.” Equally important to a government that will be eying more well-paying jobs in the aerospace sector for decades to come, Callaghan highlighted Canada's involvement in the JSF program. The federal government was the first nation to sign on to the U.S. partnership and to date “more than 110 Canadian companies have contributed to the development and the production of the F-35,” he said, resulting in about US$2 billion in contracts. According to the economic impact study, conducted by Offset Market Exchange (OMX), a Toronto-based firm that helps OEMs develop their Canadian supply chains and provides analytics to ensure compliance with ITB obligations, the full impact of the program between production (2007 and 2046) and sustainment (2026 and 2058) could result in $16.9 billion to Canada's GDP. Though contracts are awarded on a “best value” basis among all participating countries, Canadian companies have proven their ability to compete and deliver quality, he added. And suppliers would be building parts not just for 88 aircraft, but likely for over 3,000. With the F-35 manufactured in the U.S. and many sustainment hubs already selected, several Canadian companies have been raised concerns about access to high-value in-service support work. Though Callaghan wouldn't commit to specifics, he noted that more than 2,500 F-35s could be operating in North America past 2060, resulting in “a large number” of potential sustainment opportunities. “I think Canadian industry is in a very good position to capture quite a few of those contracts,” he said. If Canada opts for another aircraft, the current contracts would be honoured “to their conclusion,” but would then be placed up for best value bids to JSF nations, he added. Though Lockheed Martin is still ramping up production and addressing software issues, the F-35 is a rapidly maturing program. Over 550 aircraft have been delivered and the entire fleet has accumulated over 300,000 flight hours. Eight services, including five outside of the U.S., have declared initial operating capability and the Royal Australian Air Force is expected to do so before the end of 2020. F-35s have been part of operations and joint and international exercises. Both Norway and Italy have conducted NATO Iceland air policing with their fleets. “These are indications of the maturity of the program,” said Callaghan. “We are a mature program that is really hitting stride.” https://www.skiesmag.com/news/f-35-impact-canadas-economy/

  • Construction begins on new NORAD Quick Reaction Alert facility at Canadian Forces Base Bagotville

    August 12, 2024 | Local, Aerospace

    Construction begins on new NORAD Quick Reaction Alert facility at Canadian Forces Base Bagotville

    News release August 12, 2024 – Bagotville, Quebec – National Defence / Canadian Armed Forces Today, Marie-France Lalonde, Parliamentary Secretary to the Minister of National Defence, on behalf of the Honourable Bill Blair, Minister of National Defence, announced the beginning of construction on a new Quick Reaction Alert (QRA) facility at Canadian Forces Base (CFB) Bagotville.  This facility will enable Canadian Armed Forces (CAF) members to posture and deploy Canada’s incoming fleet of CF-35A fighter jets in a flight-ready state in support of North American Aerospace Defense Command (NORAD) operations. The new 7,400 m2 QRA facility at CFB Bagotville will include aircraft hangar bays, office space and sleeping quarters for personnel, and a 17,000 m2 secure fenced compound surrounding the facility. Once completed, it will help CAF personnel support Canada and the NORAD mission and quickly respond to any threats in North American airspace.   Construction is estimated at approximately $120 million and will sustain more than 600 jobs in the region. The facility is expected to be completed in 2027. The design and construction contract has been awarded to Pomerleau Inc of Lévis, QC.  This investment is part of Canada’s $38.6 billion NORAD Modernization Plan, announced by the Government of Canada in June 2022. This represents the most significant upgrade to Canada's NORAD capabilities in almost four decades. In particular, the QRA facility is part of the NORAD Modernization Plan’s Defence of Canada Infrastructure Project (DCFI), which commits funding to upgrade fighter infrastructure and NORAD QRA capabilities at bases across Canada to operationalize and employ the CF-35A for continental defence. This project will provide Canadian Armed Forces personnel with the infrastructure they need to support the NORAD mission, including Operation NOBLE EAGLE, which deters, detects, and defeats potential threats to U.S. and Canadian airspace 24 hours a day, 7 days a week, 365 days a year. Quotes “This investment in Bagotville will enable our personnel at the base to plan, posture, and deploy our new fleet of CF-35A fighters rapidly and effectively. Today’s milestone is a clear sign of Canada’s commitment to modernizing our NORAD infrastructure and capabilities in support of the continental defence mission. In close collaboration with our American allies, our government will continue to make the necessary investments to protect North America as our continent faces new security challenges.” The Honourable Bill Blair, Minister of National Defence “For decades, NORAD has ensured the defence of North American aerospace. Today, we are reaffirming our commitment to this unique binational command, and investing in new infrastructure so that Canadian Armed Forces members can effectively deploy fifth-generation fighter jets in support of NORAD’s mission. Our government will continue to invest in new military infrastructure that supports the combat power of the Canadian Armed Forces.” Marie-France Lalonde, Parliamentary Secretary to the Minister of National Defence  Quick facts NORAD ensures U.S. and Canadian aerospace control, to include air defense operations, through a network of alert fighters, tankers, airborne early warning aircraft, rotary wing air interceptors, and ground-based air defense assets cued by interagency and defense radars. By using this network of sensors, NORAD detects airborne objects approaching North America and conducts its air defense mission by tracking, identifying, and taking appropriate actions. Appropriate actions may include, but are not limited to, monitoring a track, scrambling fighters to intercept and identify an approaching aircraft, and/or escorting an aircraft through an Air Defense Identification Zone (ADIZ) or a Temporary Flight Restriction Area. In June 2022, the Minister of National Defence announced funding for Canada's continental defence capabilities, including to modernize the North American Aerospace Defence Command (NORAD). This represents the most significant upgrade to Canada's NORAD capabilities in almost four decades. NORAD modernization will ensure that the CAF can sustain a strong military presence across the country, including in Canada’s North, through investments in infrastructure and support capabilities. The two main operating bases for Canada’s fighter aircraft are 4 Wing Cold Lake and 3 Wing Bagotville. As announced in January 2023, Canada is acquiring a new fleet of 88 F-35 aircraft, which will be known as the CF-35A by the Royal Canadian Air Force. 36 of the 88 incoming CF-35As will be stationed at 3 Wing Bagotville, and the remaining (52) will be stationed at 4 Wing Cold Lake. CFB Bagotville opened in 1951 as a training base for the squadrons serving with the Canadian Division in Europe to support the air defence operations of the newly formed Canadian and American forces (which became NORAD in 1958). Following the September 11, 2001, attacks, NORAD established Operation NOBLE EAGLE. Operation NOBLE EAGLE is the name given to all North American Aerospace Defense Command (NORAD) aerospace warning, control, and defense missions in North America. Through Operation NOBLE EAGLE, NORAD deters, detects, and defeats potential threats to U.S. and Canadian airspace 24/7/365. CAF personnel at 3 Wing Bagotville continue to play a critical NORAD role in helping monitor and respond to potential threats.  A modified design-build approach is being used for this project. This means that the project’s design and construction have both been awarded to one successful bidder under one single contract, as opposed to the traditional method, which contracts separately for design and construction. The facility will be constructed to LEED Silver standards and will use energy efficient options wherever possible. By modernizing and greening our defence infrastructure, we are supporting the needs of a modern military, while reducing our greenhouse gas emissions and saving on energy costs.  Through our updated Defence Policy—Our North, Strong and Free—Canada is building on its 2022 NORAD Modernization Plan, with a slate of new equipment and infrastructure that will strengthen our capabilities to defend Canada and North America, such as modernized infrastructure and a new fleet of airborne early warning aircraft. Canada’s efforts to bolster domestic and continental defence, including by modernizing NORAD, are also contributions to strengthening NATO’s Western Flank, and will ensure North America remains a safe base from which we can deploy forces in support of Allies and partners.
