Calixto, Monnette (SPAC/PSPC) (elle-la / she-her)

Monnette Calixto serves as a Contracting Authority within the Department of Public Works and Government Services, where she leads the acquisition of mission-critical environmental remediation services essential to maintaining federal infrastructure integrity. In this primary contracting role, she is responsible for managing the full lifecycle of procurement activities—from needs assessment and solicitation development to contract award and performance monitoring—ensuring compliance with federal regulations and alignment with the Government of Canada’s sustainability and public safety objectives. Her portfolio centers on technical services that address soil and groundwater contamination, hazardous material abatement, and site restoration at federal facilities nationwide. Calixto collaborates with a diverse range of qualified vendors specializing in environmental engineering and remediation, including firms with expertise in hazardous waste handling, geotechnical assessment, and regulatory compliance. While no single contractor dominates her award profile, she consistently engages contractors with demonstrated technical capability, environmental certifications, and proven performance on complex federal sites. Her working relationships emphasize transparency, accountability, and adherence to performance-based contracting standards. Her procurement patterns reflect a strict focus on open competition, with 100% of her acquisitions conducted without set-aside designations such as 8(a), HUBZone, or SDVOSB. This reflects a strategic decision to prioritize technical merit and operational readiness over socioeconomic preferences, ensuring the highest level of expertise is brought to high-risk environmental projects. Calixto’s primary procurement focus is exclusively under NAICS 562910—Remediation Services—where she specializes in the acquisition of contaminated site cleanup, asbestos and lead abatement, underground storage tank removal, and environmental monitoring. Her domain expertise lies in complex, regulated environmental interventions requiring specialized equipment, licensed personnel, and strict adherence to federal and provincial environmental standards. She is a trusted authority in procuring technically demanding remediation solutions that safeguard public health and federal property.
