This post extends the five-part Brookfield conflict-of-interest series with new evidence from SEC filings, the Privy Council Office's Assessment Tool, and Airbus customer data. Part 1 examined the screen. Part 2 examined the lobbying data. Part 3 examined the policy matrix. Part 4 examined the international precedents. Part 5 examined the enforcement office. We also looked into Carney's Westinghouse interest in a post about the PM's National Electricity Strategy.

Mark Carney holds stock options and carried interest in Brookfield. Brookfield just bought one of the world's largest A220 customers. Every A220 is built at Mirabel. More A220 orders mean a healthier production line, which makes Brookfield's aviation holdings more valuable, which makes Carney's entitlements worth more. Four weeks after the Brookfield A220 deal closed, Carney flew to Mirabel to sell 150 more of them. Prepare for takeoff.

On April 8, 2026, a consortium led by Sumitomo Corporation, SMBC Aviation Capital, Brookfield, and Apollo completed its acquisition of Air Lease Corporation — renamed Sumisho Air Lease — for $28.2 billion in enterprise value. Air Lease was one of the world's largest customers for the Airbus A220, with 76 firm orders, every one of them built at the Mirabel, Quebec assembly line.

Four weeks later, on May 6, Prime Minister Mark Carney stood in the Airbus hangar at Mirabel to announce 150 new A220 orders from AirAsia — what he called "the largest order of Canadian aircraft in history." Within 48 hours, Export Development Canada confirmed it was in financing talks for the deal.

The Privy Council Office's own Assessment Tool — the framework designed to determine whether Carney's ethics screen should be triggered — lists "the airline industry" as one of six sectors requiring case-by-case scrutiny. The tool's guidance specifically references "investments in airlines/aviation" and "airline ownership rules/industry consolidation."

These are three documented facts. Let's examine what connects them.

What Brookfield bought on April 8

The Brookfield-Apollo-Sumitomo-SMBC acquisition of Air Lease Corporation was announced on September 1, 2025. Shareholders approved the merger on December 18, 2025, with 80.7% voting in favour. The deal closed on April 8, 2026.

The ownership structure, from regulatory filings:

Partner	Voting Rights	Economic Interest
Sumitomo Corporation	47.5%	37.5%
SMBC Aviation Capital	5.0%	25.0%
Apollo	23.75%	18.75%
Brookfield	23.75%	18.75%

Brookfield holds structured equity — 23.75% voting rights but 18.75% economic interest. Sumitomo holds a call option from year seven to acquire Brookfield's and Apollo's stakes. At 18.75% of a $28.2 billion enterprise, Brookfield's exposure is approximately $5.3 billion. Brookfield closed this acquisition four weeks before Carney stood in the hangar.

Air Lease's final quarterly filing before delisting — the Q3 2025 10-Q — reported a fleet of 503 aircraft with a net book value of $29.5 billion, serving 108 airline customers in 55 countries. The A220 was its fastest-growing fleet segment.

Metric	FY2024 (10-K)	Q3 2025 (10-Q)
A220 fleet (delivered)	29 aircraft	40 aircraft
A220 as % of fleet	5.9%	7.9%
A220 on order	46 aircraft	34 aircraft
Total order commitments	$17.1B	$13.4B

The company had grown its A220 fleet from 29 to 40 aircraft in under a year, with 34 more on order. All 2025 and 2026 A220 deliveries were 100% placed — airlines were contractually waiting for these planes. Every delay at Mirabel cost Brookfield's new company money.

Air Lease's confirmed A220 lessees, drawn from press releases and industry data:

Airline	Country	Aircraft
ITA Airways	Italy	~15
Bulgaria Air	Bulgaria	7
TAAG Angola Airlines	Angola	6
Croatia Airlines	Croatia	6
Czech Airlines/Smartwings	Czech Republic	4
Cyprus Airways	Cyprus	2

AirAsia does not lease aircraft from Air Lease. Brookfield benefits here because more A220 orders mean a healthier production line, faster deliveries, and higher asset values for Sumisho's fleet — not because AirAsia is a customer. I will return to this distinction.

Every one of those jets is built in Mirabel

Airbus operates two A220 assembly lines. The original facility in Mirabel, Quebec serves all non-US customers — including leasing companies. A second line in Mobile, Alabama serves US airlines only.

Air Lease Corporation's A220 fleet is entirely Mirabel-built. This is a function of the geographic allocation rule: lessors are not US airline customers, and their A220s are assembled in Quebec regardless of where the leased aircraft ultimately operates. The Airbus customer data confirms this.

Sadly, the Mirabel line is not in good shape. Combined A220 production across both sites runs at roughly 7 to 8 aircraft per month. Their break-even is about 14. Mirabel's own target is 10 per month but the line has never reached it. The A220 program has never turned a profit. Mirabel produces at half the rate it needs to stop losing money.

The constraints are well-documented: Pratt & Whitney's GTF engine recall has grounded roughly 1,200 engines across the family, with shop visits averaging over 300 days. "Glider" aircraft — assembled airframes sitting engineless on the tarmac — are a recurring feature of the production line. Airbus filed a damages claim against Pratt & Whitney in March 2026.

Against that backdrop, the AirAsia order was a godsend, adding 33% to the A220 backlog and pushing it past 600 aircraft. All 150 aircraft will be Mirabel-built — AirAsia is a non-US customer. Aviation analyst Ernest Arvai told The Deep Dive that the order "puts the program on the path to profit." A production line that has never turned a profit just added 150 aircraft to its order book.

Air Lease's 10-K filing had described production delays at Mirabel as a material risk:

"Airbus Canada Limited Partnership ('Airbus Canada') manufactures a majority of our Airbus A220 aircraft in Mirabel, Quebec"

"As a result of continued manufacturing delays and supply chain constraints described herein, the Company's aircraft delivery schedule could continue to be subject to material changes and delivery delays are expected to extend for at least the next three to four years."

Management had already adjusted its 2026 A220 delivery expectation from six aircraft to two or three, pushing deliveries into 2028-2029. Sumisho Air Lease has 34 A220s on order and airlines under contract waiting for them. When the production line speeds up, those planes arrive on schedule, the airlines start paying lease revenue, and the aircraft on Sumisho's books are worth more. When it slows down, airlines can invoke cancellation clauses, delivery revenue stalls, and the fleet depreciates. The AirAsia order commits Airbus to expanding Mirabel output. Sumisho's entire A220 book benefits.

What happened at Mirabel on May 6

The PMO press release for the AirAsia announcement listed the attendees: Prime Minister Carney, Quebec Premier Christine Frechette, Industry Minister Melanie Joly, AirAsia CEO Tony Fernandes, Airbus Commercial Aircraft CEO Lars Wagner, and Airbus Canada CEO Guillaume Chevasson. Over 4,600 workers watched from the hangar floor.

Carney was not a passive attendee. He had cultivated the deal personally. At the ASEAN Summit in Kuala Lumpur in October 2025, he met Tony Fernandes to discuss a large A220 order. The deal had been in the works for months by the time Carney arrived at Mirabel to announce it.

His remarks, reported by CBC, framed the deal in geopolitical terms:

"We shared a vision of deepening ties between those countries that, in this crisis that we're still living through, are choosing to build in the face of adversity."

Fernandes was equally direct about the Prime Minister's role: "I think Mark Carney's great for our brand. He's very popular in Asia. He's been a great ambassador for Canada." And: "If we could support him, why not?"

Lars Wagner, CEO of Airbus Commercial Aircraft, addressed the government relationship explicitly: "Government support is the backbone of the innovation we see in this hangar, and we don't take this for granted."

No new federal money was announced at the event. But within 48 hours, EDC confirmed it was in financing talks with Airbus for the AirAsia order — a deal with a list price of approximately $19 billion, and estimated net value of $6.8 billion, with deliveries beginning in 2028.

The Assessment Tool says to check for this

The Privy Council Office provided the ETHI committee with an "Assessment Tool on the Application of the Prime Minister's Conflict of Interest Screen." This document is the operational framework — the step-by-step procedure that PCO analysts are supposed to follow when a decision involving the Prime Minister might touch Brookfield's interests.

The tool's Part B — "Matters Requiring Assessment" — identifies six sectors where Brookfield's interests are "largely concentrated" and where "case-by-case assessment" is required:

1. Real Estate
2. Mortgage Insurance (Sagen MI)
3. The airline industry — "policy/spending discussions and decisions related to issues such as investments in airlines/aviation; airline ownership rules/industry consolidation as well as fare pricing"
4. Expansion of the nuclear industry (Westinghouse)
5. Expansion/investment in renewable energy sector (Solar/Wind/Hydro)
6. Credit card industry (Stripe)

The airline industry entry references exactly what happened at Mirabel: investments in aviation.

But the airline sector did not exist in the earliest known draft of this Assessment Tool. The Sabia transition binder, obtained through an ATIP request and dated June 25, 2025 (page 115), contains a draft Assessment Tool with no sector list at all. The draft references only real estate, infrastructure, and payments as areas of concern. The airline industry sector was added between that June 2025 draft and the version provided to the ETHI committee — a period that includes the September 1, 2025 announcement of the Brookfield/Apollo/Sumitomo acquisition of Air Lease Corporation.

Someone at PCO identified aviation as a Brookfield exposure concern for Mark Carney. That identification was correct. The exposure was identified clearly enough to write into the tool. What happened at Mirabel is undocumented.

The Assessment Tool walks analysts through seven questions. Let's apply it to the May 6 event:

Question 1: Is the Prime Minister involved? Yes. Carney attended, spoke, and had personally cultivated the deal since October 2025.

Question 2: Does it involve direct engagement with an Annex A company? No. The full Annex A — all three parts — is public on the ethics commissioner's registry. Sumisho Air Lease and Castlelake do not appear in Part A (management role), Part B (lobbyist registry), or Part C (abundance of caution). The list was set as of January 2025, eight months before the Brookfield/ALC acquisition was announced. The double-check described by Marc-Andre Blanchard at the ETHI committee — where staff verify whether a meeting involves an Annex A entity — would not have caught this.

Question 3: Are the interests of one of the Companies involved? The airline industry is a flagged sector. Brookfield, through Sumisho Air Lease, holds 18.75% economic interest in one of the largest A220 customers. An order that adds 33% to the backlog and puts the production line "on the path to profit" engages that interest directly.

Question 4: General application? The tool's own guidance states that decisions applying "to a regulated activity and to an identifiable group" are not general application. Aircraft manufacturing and leasing is both.

Question 5: Broad class? A220 lessors include Air Lease, Aviation Capital Group, Azorra, Macquarie AirFinance, and Nordic Aviation Capital — a small group. The tool's guidance states that "if the decision applies to a small group, the matter does not apply to a broad class."

Question 6: Disproportionate? Air Lease holds 76 of approximately 905 A220 firm orders — about 8.4% of the total, and the largest single lessor customer. The tool's own guidance on the mortgage insurance sector notes that a market with two main players triggers the screen. The A220 leasing market is similarly concentrated.

Question 7: Direct link? The Prime Minister's sustained personal involvement — from the ASEAN Summit meeting through the Mirabel announcement — followed by EDC financing talks, creates a plausible direct link between his involvement and the opportunity to further the Companies' interests.

Seven questions. The Prime Minister's own framework produces uncomfortable answers on most of them. Did anyone at PCO actually run this analysis before Carney flew to Mirabel?

The Castlelake acquisition no one has connected

The Brookfield aviation exposure does not end with Sumisho Air Lease.

On September 17, 2024, Brookfield completed its acquisition of a 51% stake in Castlelake for $1.5 billion. Castlelake is a Minneapolis-based alternative investment manager that has deployed $21 billion in aviation investments since 2005, acquired more than 650 aircraft, and maintains relationships with approximately 200 airlines worldwide. It operates Merit AirFinance, an aviation lending platform, and manages $24 billion in assets.

AirAsia's known lessors include Castlelake. This is a relationship that predates the Brookfield acquisition, but Brookfield's majority ownership of Castlelake means the AirAsia deal — and the EDC financing talks that followed — touches a second Brookfield portfolio company, not only the Sumisho Air Lease interest in production line health.

Combined, Brookfield's aviation footprint through Sumisho Air Lease and Castlelake includes economic interest in roughly 500 owned aircraft (Sumisho), 650+ aircraft acquired through Castlelake's funds, and over $28 billion in new technology aircraft orders. Brookfield is now one of the largest private aviation investors on the planet. The Assessment Tool's "airline industry" sector flag was written for precisely this kind of concentrated exposure.

If the screen wasn't triggered here, when would it be?

EDC has financed Brookfield before

Export Development Canada's involvement in the AirAsia deal is not a first encounter with either Brookfield or the A220.

EDC's confirmed financing history with Brookfield entities:

Year	Brookfield Entity	Amount	Purpose
2009	Brookfield Asset Management (DIP Fund)	$450M–$1B (EDC as lead LP)	Global debtor-in-possession financing
2008	Brookfield Renewable Power	US$120M	Brazil hydroelectric
2011	Brookfield / Brookfield Rail	Undisclosed	Australia rail
2014	Brookfield Asset Management	Undisclosed	Unknown
2017	Brookfield Renewable Partners	$25–50M	Ireland wind farm
2018	Brookfield Infrastructure Partners	Undisclosed	Unknown
May 2023	Brookfield Corporation	Undisclosed	UK foreign investment
May 2023	Brookfield Business Partners	Undisclosed	Australia foreign investment
Dec 2024	Westinghouse (51% Brookfield)	US$1.45B LOI	Poland AP1000 nuclear plant

EDC has also financed A220 purchases directly. In 2020 and 2021, EDC provided approximately $1.1 billion in financing for 33 Air Canada A220-300s — aircraft built at Mirabel. Both facilities were repaid by August 2023. EDC has financed Brookfield and the A220 program separately. The AirAsia deal converges both.

The AirAsia order, if financed through EDC, would be the largest single transaction in the agency's history of Brookfield-related financing, and by a wide margin. EDC is structured as an arm's-length Crown corporation, and its financing decisions are made independently of the Prime Minister's Office. That institutional independence is the standard counterargument. But the Assessment Tool does not exempt arm's-length agencies from its analysis — it asks whether the Prime Minister's involvement creates "an opportunity to further one of the Company's interests," regardless of the institutional mechanism.

Carney personally courted the AirAsia deal at an international summit, flew to Mirabel to announce it, and his government moved to finance it within 48 hours. He seems involved.

What we don't know

Several questions remain unanswered, and the answers are obtainable through Access to Information requests and parliamentary questions:

Was the Assessment Tool applied to the Mirabel announcement? The PCO has confirmed that the screen has been triggered six times. There is no public record of whether the Assessment Tool was applied to Carney's Mirabel trip and, if so, what conclusion was reached. A PMO briefing note for the visit would typically include a "conflicts" or "sensitivities" section — that document is obtainable through ATIP.

When exactly was the airline industry sector added to the Assessment Tool? The June 2025 draft had no sector list. The committee version has six sectors. The additions track to the period after the Brookfield/ALC acquisition was announced. The intermediate drafts — and the memos that informed the additions — would show whether PCO connected the A220 exposure to the screen proactively or after the fact.

Which of the six triggers involved aviation? Of the six times the screen has been invoked, the subject matter has not been disclosed. If none involved aviation — despite the sector being flagged in the Assessment Tool — that is itself a finding about how the tool operates in practice. Six sectors flagged for scrutiny. Six times the screen was triggered. Whether those two lists overlap at all remains undisclosed.

These are questions for the ETHI committee and for independent journalists who file ATIPs. They are not rhetorical.

What we do know

Brookfield holds an 18.75% economic interest in Sumisho Air Lease, which has 34 A220 aircraft on order, all built at Mirabel, with deliveries that the company's own SEC filings describe as subject to "material changes and delivery delays." Brookfield also holds a 51% stake in Castlelake, which has $21 billion in aviation investments and a leasing relationship with AirAsia.

Neither Sumisho Air Lease nor Castlelake appears anywhere on the public Annex A — not in Part A (management role), Part B (lobbyist registry), or Part C (abundance of caution). The list was frozen in January 2025, before the Brookfield/ALC acquisition was announced. The screen's first line of defence, the Annex A name-check, does not cover Brookfield's aviation holdings. The only safety net is the Assessment Tool's sector analysis.

The Prime Minister personally cultivated the AirAsia-Airbus deal beginning at the ASEAN Summit in October 2025, attended the announcement at Mirabel on May 6, 2026, and presented it as a signature achievement. EDC moved to finance the deal within 48 hours.

The PCO's own Assessment Tool identifies the airline industry as a sector requiring case-by-case assessment under the ethics screen. The tool's seven-question framework, applied straightforwardly to the Mirabel event, produces answers that at minimum warrant analysis. Whether that analysis was conducted is unknown.

The ethics screen was designed to catch exactly this kind of exposure — a Prime Minister whose financial entitlements connect to a sector in which he is personally advancing government policy. The screen's administrators added the airline industry to the Assessment Tool's sector list for a reason. The question is whether the institution they built actually used it. Are we to be left wondering whether the Prime Minister's public deals are enriching his private holdings?

That is a question for Parliament.
