Who owns Kiewit-Dufferin Midtown Partnership
One company in the researched set discloses a stake in Kiewit-Dufferin Midtown Partnership, none of it sized by anyone who discloses it. Kiewit-Dufferin Midtown Partnership is private, so no 13F reports it: a 13F covers exchange listed positions only. These figures exist because each holder disclosed the stake in its own filings.

Kiewit-Dufferin Midtown Partnership is a Canadian construction joint venture formed by Peter Kiewit Sons and Dufferin Construction to deliver the Ontario Ministry of Transportation's Midtown Bridge Replacement Project, a bundled contract worth about 180 million Canadian dollars covering five Highway 417 overpasses in central Ottawa at Rochester, Booth, Bronson, Percy and Crescent streets. The work replaced each crossing with two new spans of rigid frame construction designed for a 75 year service life, and it was procured under a construction manager and general contractor model that brought the builders into the design process from the outset rather than tendering a finished design. The Rochester and Booth structures were finished in 2022, Bronson and Percy in 2023 and Crescent in 2024. The partnership has also bid on other Ontario highway work, including the QEW and Credit River improvement project.

Kiewit-Dufferin Midtown Partnership files nothing with the SEC, so none of this comes from a filer record. The description was written for this site in August 2026 from MTO, Kiewit-Dufferin team wrap rapid bridge job in Ottawa (Daily Commercial News), Teams Shortlisted and Request for Proposals Issued for QEW / Credit River Improvement Project (Infrastructure Ontario) and CRH plc Form 10-K for 2024, Exhibit 21.1 principal subsidiaries and joint ventures (SEC). The ownership figures below come from the holders' filings instead, and are sourced row by row.
The disclosed stakes
One row per position. Where a holder reports the same company in two share classes, both rows are shown rather than summed, because the class is part of a position's identity.
Where each figure comes from
A private stake has no ownership form behind it, so the source is always the holder's own filing or disclosure. Anything modelled says so, with the arithmetic.
- CRH plc. Canada. Products/services: Construction. Not consolidated: accounted for under the equity method. CRH's FY2025 10-K reports a single combined 'Equity method investments' balance of $737 million as of 31 Dec 2025 ($620 million at 31 Dec 2024, $649 million at 31 Dec 2023, per the Adjusted ROIC reconciliation in Item 7 MD&A) covering ALL of the entities in this exhibit table together. The filing does not disclose a per-investee carrying value, so value_usd is null here per the combined-balance rule; the combined figure is recorded in notes and unknowns, not assigned to this row. sourcesource 2
What this page is not
It is not a complete register. It lists the holders who happen to be inside the researched set and disclosed the stake themselves. A private company can have many other shareholders, and nothing here rules them out: venture investors, founders and employees usually appear in no public filing at all. Percentages are of Kiewit-Dufferin Midtown Partnership where a holder stated one, and are missing where no holder did.
