Overview
Tervita was a Canadian energy and environmental services company whose business combined industrial waste management with services supporting oil and gas operations. Its activities included oil-field waste disposal, landfill remediation, demolition, metals recycling, water treatment, civil and environmental construction, construction drilling, oil-sands-related work, and oil-spill cleanup. The company served customers through operations in Canada and the United States. The business originated in Alberta in 1979, when David P. Werklund and Gordon Vivian established Concord Well Servicing in Valleyview. The company’s early activities were connected to well servicing and the needs of the petroleum sector. In 1984, with investment from Werklund, Canadian Crude Separators Corporation, commonly known as CCS Corp., was formed to provide oil-waste services. This created the corporate platform from which the later Tervita group developed. Hazco, an environmental and water-services business, was established in 1989. During the following years, CCS and Hazco expanded through acquisitions of companies involved in energy-related waste, environmental services, and industrial operations. CCS became publicly traded in 1994 and acquired Hazco in 2004, bringing oil-waste and broader environmental capabilities under common ownership. In 2007, CCS changed its name to CCS Corporation and returned to private ownership. In 2012, twelve businesses operating under CCS Corporation, including CCS Midstream Services and Hazco, were brought together under the Tervita name. The consolidation presented Tervita as an integrated provider rather than a collection of separate regional or specialist businesses. Its scope covered the treatment, recovery, transportation, disposal, and remediation of materials associated with energy production and other industrial activity. Tervita became the subject of an important Canadian competition-law case after acquiring Complete Environmental Inc. for approximately CAD 6 million. The acquisition enabled Tervita to develop a landfill in northeastern British Columbia. The Competition Bureau challenged the transaction on the grounds that Tervita would control all three landfills in the region and could thereby reduce competition. In January 2015, the Supreme Court of Canada ruled in Tervita’s favour. The decision was significant because it addressed how Canadian merger law should treat a relatively small acquisition and clarified the evidentiary framework for assessing whether a transaction substantially prevents competition. On July 19, 2018, Tervita Corporation and Newalta Corporation announced the completion of their previously announced business combination. The combined company continued operating under the Tervita Corporation name, broadening its industrial and energy-services footprint. Tervita subsequently ceased to be an independent company when Secure Energy Services acquired it in an all-stock transaction that closed on July 2, 2021. The transaction ended Tervita’s existence as a standalone publicly traded corporate group, although its assets, operations, and service capabilities became part of Secure’s business.
History
Tervita’s history began in Alberta’s oil-field services sector. In 1979, David P. Werklund and Gordon Vivian founded Concord Well Servicing in Valleyview, Alberta. The company initially focused on well-servicing activities and developed within the wider petroleum-services economy. In 1984, Canadian Crude Separators Corporation, generally known as CCS Corp., was established with investment from Werklund. CCS provided services for oil waste and became the principal corporate vehicle for a growing portfolio of energy and environmental businesses. Hazco was formed in 1989 to provide water and environmental services, extending the group beyond its original oil-waste focus. CCS became publicly traded in 1994. Over the next decade, CCS and Hazco acquired businesses associated with energy waste, environmental management, and related industrial services. CCS acquired Hazco in 2004, combining the two organizations. In 2007, the company renamed itself CCS Corporation and went private. The Tervita identity was created in 2012, when twelve companies operating under CCS Corporation were combined under one organization. The group included CCS Midstream Services and Hazco. Its service portfolio covered oil-field waste disposal, landfill and remediation work, demolition, metals recycling, water treatment, civil and environmental construction, construction drilling, oil-sands exploration, and oil-spill response. The combined structure allowed the company to present a broader offering to energy-sector and industrial customers across Canada and the United States. A major legal event followed Tervita’s acquisition of Complete Environmental Inc. for approximately CAD 6 million. The transaction related to the development of a landfill in northeastern British Columbia. The Competition Bureau argued that Tervita would control all three landfills in the region and that the acquisition could eliminate competition. In January 2015, the Supreme Court of Canada decided in Tervita’s favour. The case became influential in Canadian competition law because it concerned a comparatively small acquisition and established guidance on the evidence required to demonstrate that a transaction would substantially prevent competition. On July 19, 2018, Tervita Corporation and Newalta Corporation completed a previously announced business combination. The enlarged organization continued under the Tervita Corporation name and combined complementary industrial and energy-services operations. Tervita’s independent corporate life ended on July 2, 2021, when Secure Energy Services acquired the company through an all-stock transaction. After the acquisition, Tervita was no longer an independent publicly traded company. Its operating assets and service capabilities were incorporated into Secure Energy Services.
