1000169511 Ontario Inc.

1000169511 Ontario Inc., doing business as Proserv Window Cleaning Services, is a Canadian for-profit corporation based in Ottawa, Ontario that provides facility maintenance and janitorial services to U.S. Department of State locations, operating exclusively as a prime contractor under full-and-open competition with no set-aside activity across its federal footprint.

Proserv's capability portfolio centers on window cleaning, stainless steel cleaning, lawn maintenance, snow removal, and fuel procurement services for U.S. Embassy facilities. Recent representative awards include a $154,464.83 firm fixed-price definitive contract from the Bureau of Western Hemisphere Affairs (awarded August 21, 2026, running through August 31, 2027) for U.S. Embassy Chancery window and stainless steel cleaning services at 2323 Riverside Drive, Ottawa; a $29,590.36 fixed-price definitive contract from the Bureau of Overseas Building Operations (awarded July 22, 2024, completed October 30, 2024) for lawn maintenance and snow removal at an Embassy facility in Ottawa; and two Blanket Purchase Agreements from U.S. Embassy Ottawa for mail and pouch charges and fuel charges, each with $15,000 ceilings awarded in October 2024 and running through September 2025.

Customer concentration is narrow and agency-specific. All seven awards across the vendor's recent footprint flow from the Department of State, with the Bureau of Western Hemisphere Affairs accounting for four awards carrying $463 thousand in combined potential value (89% of the portfolio), while U.S. Embassy Ottawa and the Bureau of Overseas Building Operations split the remainder. Activity is sparse and episodic — one award in 2018, one in 2020, one in 2021, two in 2024, and one in 2026 — with $523 thousand in combined potential value and $361 thousand obligated across the seven-award set. One award carrying $154 thousand in potential value reaches completion inside the next twenty-four months. The vendor holds no sub-award relationships and maintains no position on governmentwide vehicles or agency-wide IDIQs; all work flows through direct definitive contracts and embassy-level BPAs.
