Overview
Discovery Air was a Canadian aviation-services company established in 2004 and built through a portfolio of operating businesses rather than around a single airline network. Its activities included fixed-wing and rotary-wing charter, passenger and cargo transportation, northern medevac, helicopter utility work, remote-site logistics, mining-support services, fire suppression and military air-combat training. The group primarily served corporate and government customers in Canada, particularly in northern and remote regions where aviation was essential to mineral exploration, infrastructure work, emergency response and community access. The company was created by David Taylor and expanded rapidly through acquisitions. In late 2004 it acquired half of Hicks & Lawrence, later known as Discovery Air Fire Services, and purchased the remaining interest in 2005. Discovery Air went public in 2006 and subsequently acquired Great Slave Helicopters, Air Tindi, selected Walsten Air Service wheel-division assets, Top Aces and Discovery Mining Services. These transactions gave it exposure to helicopter operations, scheduled and charter aviation, aerial firefighting, defence services and remote mining logistics. Its Northern Services activities were centered on Great Slave Helicopters, Air Tindi and Discovery Mining Services, while other subsidiaries supplied technical, fire, defence and training capabilities. The operating portfolio covered a broad range of specialist missions. Great Slave Helicopters provided visual- and instrument-flight-rule helicopter services, charter and cargo operations, utility flying and support for government and resource-sector customers. Air Tindi, based in Yellowknife, operated fixed-wing aircraft for scheduled and on-demand services, cargo, passenger transport and medevac missions in northern and western Canada. Discovery Mining Services supported exploration clients with remote camps, expediting, logistics and staking. The group also developed technical-services and innovation initiatives, including an abandoned proposal to acquire hybrid airships for northern operations. Growth was accompanied by governance disputes, restructuring and financial pressure. The company experienced layoffs at Air Tindi in 2012, divested Discovery Air Technical Services in 2016 and sold Discovery Air Fire Services in 2017. It also completed a privatization transaction in 2017. A contested restructuring involving Discovery Air Defence Services and creditor Clearvest contributed to shareholder conflict and weakened the parent company's position. In March 2018 Discovery Air sought protection under Canada's Companies' Creditors Arrangement Act after reporting approximately C$149 million in debt. The Toronto Stock Exchange delisted the company on April 27, 2018. Court-supervised sale proceedings followed, and key northern businesses were subsequently separated from the former group. Great Slave Helicopters entered its own restructuring and was sold in November 2018. Discovery Air therefore survives primarily as a historical corporate brand associated with Canadian specialized and northern aviation, rather than as an operating airline.
History
Discovery Air was founded in 2004 by David Taylor. The company was incorporated by Pacific & Western Bank of Canada, where Taylor was president and chief executive. Its first major transaction came in December 2004, when it acquired a 50 percent interest in Hicks & Lawrence, an aviation fire-services business. Discovery Air purchased the balance in 2005, bringing the operation fully into the group and later renaming it Discovery Air Fire Services. The company completed an initial public offering in April 2006 and used the proceeds and subsequent financing to assemble a diversified aviation platform. Great Slave Helicopters was acquired in June 2006, followed by Air Tindi in December. In 2007 Discovery Air acquired wheel-division assets from Walsten Air Service through Hicks and Lawrence, and in August it purchased Top Aces, which was later renamed Discovery Air Defence Services. Discovery Mining Services joined the group in January 2008. These acquisitions positioned Discovery Air across helicopter services, northern passenger and cargo operations, aerial firefighting, defence training and mineral-exploration support. The expansion period was followed by internal conflict and management change. In 2008 Taylor stated that he and his allies had been removed from the board and management and criticized the succeeding leadership for damaging the business and shareholder value. Discovery Air announced an interim chief executive officer in September of that year. In January 2009 the Government of the Northwest Territories provided a C$34 million loan; the loan was reported as repaid by 2012. The company also announced new financial officers in November 2009. Discovery Air continued adding capabilities during the early 2010s. Discovery Air Technical Services began operations in 2010. In 2011 the company created Discovery Air Innovations and entered a provisional arrangement with Hybrid Air Vehicles concerning as many as 45 hybrid airships for northern use. The plan was not finalized, and Discovery Air let the arrangement lapse in August 2012. Discovery Air Fire Services also launched Discovery Aviation Academy in 2011. Great Slave Helicopters acquired Servicios Aéreos Helicopters in Chile in 2012, later operating it as Helicopters.cl SpA after the sale, and acquired Northern Air Support in February 2012. Discovery Air acquired Advanced Training Systems International in 2013. The group operated through several business units. Great Slave Helicopters supplied helicopter charter, cargo, passenger, utility and government services across northern Canada and worked with a network of regional and Indigenous aviation partnerships. Air Tindi was headquartered at Yellowknife Airport and provided scheduled and charter services, cargo transport and medevac operations across northern and western Canada. Discovery Mining Services, founded in 1991 before its acquisition, supported mineral and diamond exploration through remote camps, logistics, expediting and staking. The broader portfolio also included technical services, fire suppression and defence aviation training. The group supported mining, oil and gas, power-line construction, aerial surveys, seismic work, tourism, wildlife services and emergency medical transportation. Financial pressure became more pronounced later in the decade. Premier Aviation acquired Discovery Air Technical Services in 2016, and Discovery Air sold Discovery Air Fire Services in 2017. The company also completed a privatization transaction in 2017. Later that year, changes surrounding the financing and ownership of Discovery Air Defence Services created a dispute involving directors, creditors and shareholders. The proposed transaction involving Clearvest, a major creditor, was criticized as having proceeded without the approvals some investors believed were required under debt covenants. The conflict contributed to an organized effort by investors to resist the proposed asset and debt arrangements. In March 2018 Discovery Air sought protection under the federal Companies' Creditors Arrangement Act after declaring approximately C$149 million in debt. Clearvest, identified as the largest creditor with approximately C$72.7 million, proposed acquiring Air Tindi, Great Slave Helicopters and Discovery Mining Services. A court-supervised sale-solicitation process was conducted in April. Discovery Air was delisted from the Toronto Stock Exchange on April 27, 2018. Great Slave Helicopters later obtained creditor protection and undertook its own restructuring. In November 2018 it was sold to Great Slave Helicopters 2018 Ltd., a company owned by Pat Campling Jr. The breakup and restructuring of its operating businesses marked the end of Discovery Air as an independent aviation-services group.
