Inside the Toronto Stock Exchange's annual ranking of its fastest-scaling companies — the numbers behind a record year, and what they do and don't tell investors.
The Toronto Stock Exchange has released the 2026 TSX30, its annual ranking of the 30 best-performing TSX-listed companies measured by three-year dividend-adjusted share price performance, and this year’s group set a record. The 2026 cohort delivered an average return of 785 per cent — close to double the 431 per cent average recorded by the 2025 list.
The ranking was announced on September 9, 2026, and is built on S&P Capital IQ dividend-adjusted price data as at June 30, 2026. Together, the 30 companies on the list represent $252.6 billion in market capitalization and added $225.7 billion in value over the three-year measurement window.
Celestica Tops the Ranking for a Second Straight Year
Celestica finished first on the 2026 TSX30, repeating its position at the top of the 2025 edition. Back-to-back first-place finishes are notable because the ranking uses a rolling three-year window: to stay at number one, a company has to keep compounding gains against a base that is already elevated by its previous run.
The exchange did not publish, in the material reviewed for this report, a company-by-company breakdown of returns beyond the top position. Sector composition and the individual placements of the remaining honourees are not specified here.
Why a 785% Average Return Is the Headline Number
The average return is the single figure that separates one TSX30 vintage from another, and the jump from 431 per cent to 785 per cent in a single year is unusually wide. In practical terms, it means the cut-off to make the list rose sharply: companies that would have ranked comfortably in an earlier cohort would not necessarily qualify against this year’s field.
A few things are worth keeping straight when reading that number:
- It is an average, not a typical outcome: a ranking of the top 30 performers is a survivorship-selected group by design, and the average can be pulled upward by a handful of extraordinary results.
- It is dividend-adjusted: returns account for dividends paid over the period, not just the movement in the quoted share price.
- It is a three-year window ending June 30, 2026: the figure reflects that specific stretch of market history, including whatever starting point the mid-2023 baseline provided.
That last point matters. A three-year measurement period that begins near a market trough will mechanically produce larger percentage gains than one that begins near a peak, regardless of company execution.
$252.6 Billion in Market Cap and $225.7 Billion Created
The scale figures give the record return some substance. A combined market capitalization of $252.6 billion, built on $225.7 billion of value added across three years, tells you these are not only fast-moving small caps — the cohort as a whole grew into serious size during the period.
The gap between the two numbers is itself informative. The overwhelming majority of the group’s current market value was created inside the three-year window, which is the clearest available signal that the list is capturing companies in an active scaling phase rather than established large caps posting steady single-digit gains.
Half the 2026 Cohort Are Returning Honourees
Half of the companies on the 2026 TSX30 have appeared on a previous edition of the list. Repeat appearances are the closest thing the ranking offers to a durability test, because a company has to keep outperforming across overlapping three-year windows to stay in contention.
The other half of the list turned over, which keeps the ranking from becoming a static roll call of the same names. For readers tracking Canadian growth stories, that mix — roughly 15 returning, roughly 15 new — is a reasonable snapshot of how quickly leadership rotates on the exchange.
Fourteen TSX30 Companies Moved into the S&P/TSX Composite Index
Fourteen of the companies on the list joined the S&P/TSX Composite Index during the measurement period. That detail speaks to the graduation path the ranking is meant to illustrate: companies that grow enough in size and liquidity to meet the Composite’s inclusion standards move into Canada’s headline benchmark.
Index inclusion has practical consequences beyond prestige. Entering the Composite typically brings a company onto the radar of index-tracking funds and institutional mandates benchmarked to it, which changes the shareholder base and the trading profile. It also means those companies now contribute directly to the moves readers see when the S&P/TSX Composite records a session such as its recent 1.11 per cent drop to a one-month low.
How the TSX30 Is Measured
The methodology is deliberately narrow, which is both its strength and its limitation. The ranking is based on dividend-adjusted share price performance over three years, using S&P Capital IQ data as at June 30, 2026.
| Measure | Three-year dividend-adjusted share price performance |
| Data source | S&P Capital IQ |
| Data as at | June 30, 2026 |
| List size | 30 companies |
| 2026 average return | 785% |
| 2025 average return | 431% |
| Combined market capitalization | $252.6 billion |
| Value added over three years | $225.7 billion |
| Returning honourees | Half the list |
| Joined S&P/TSX Composite in the period | 14 companies |
Because the screen is performance-based, it does not assess profitability, revenue growth, balance sheet strength, governance, or valuation. A company can rank highly on the TSX30 while trading at a multiple that some analysts would consider stretched, and nothing in the ranking speaks to that question either way.
What the Record Cohort Signals About Canadian Listings
For a market often described as concentrated in banking, energy, and resources, a list built entirely on growth performance is a useful counterweight in the public conversation. The exchange’s framing this year — recognizing companies scaling into global leaders — leans on that idea, and the index-graduation figure gives it some evidence.
It also lands at a moment when Canadian capital markets policy is getting steady attention, from the work of bodies such as the Ontario Securities Commission’s Capital Markets Advisory Committee to ongoing debates about domestic listings, scale-up financing, and whether Canadian growth companies stay listed at home as they mature. A cohort that added $225.7 billion in value while remaining on the TSX is a data point in that discussion.
The broader trading backdrop is a separate matter. Day-to-day index direction continues to be driven by commodity prices, rate expectations, and cross-border trade conditions — the same forces shaping moves in the Canadian dollar alongside elevated oil prices — none of which the TSX30 attempts to capture.
Reading the List Without Overreading It
The TSX30 is a backward-looking performance ranking, not a forecast and not a recommendation. Past three-year returns, however large, carry no implication about future results, and the list makes no claim about whether any company is currently fairly valued. Readers considering investment decisions should seek advice from a licensed professional and do their own research on individual names.
What the 2026 edition does establish clearly is the scale of the outperformance at the top of the Canadian market over the three years to mid-2026: a record average return, a doubling of last year’s benchmark figure, and a quarter-trillion dollars of combined market value concentrated in 30 companies.
