Among the 50 Series A rounds shown, the largest disclosed amount is Reunion Neuroscience at $133M (2025-09-21). That figure dwarfs the rest of the disclosed rounds, with the next-largest disclosed amounts including Phoenix Health at $35M (2025-03-13) and several $30M rounds such as Puzzle Medical Devices ($30M on 2025-04-08) and Borealis Biosciences ($30M on 2024-12-19). At the low end, the smallest disclosed amount in the table is $3M, appearing for Cascadia Seaweed (2024-11-21), Walnut Insurance (2024-08-08), Growcer (2024-04-23), and others.
The geography is heavily Ontario-leaning, with Toronto-based companies repeatedly appearing across years (e.g., Reunion Neuroscience on 2025-09-21, Feroot Security on 2025-11-20, and Raenest on 2025-02-11). Temporally, the displayed rounds cluster into two main windows: late 2024 through early 2025 (e.g., multiple entries from 2024-12-01 to 2025-03-13) and another concentration in mid-to-late 2025 (e.g., Feroot Security on 2025-11-20 and Cove Soda on 2025-11-05). The listing spans 2024-02-22 through 2025-11-20, and includes multiple undisclosed amounts (5 of the 50 rows).

Frequently asked
What’s the biggest disclosed Series A round here, and how extreme is it versus other disclosed amounts?
Reunion Neuroscience’s $133M (2025-09-21) is the standout outlier; it sits far above the next-largest disclosed figures such as Phoenix Health at $35M (2025-03-13) and $30M rounds including Puzzle Medical Devices ($30M on 2025-04-08) and Borealis Biosciences ($30M on 2024-12-19).
Do any time windows dominate the more recent activity in this Series A Canada set?
Yes. A dense stretch runs from 2024-12-01 through 2025-03-13 (e.g., NEXT Integrative Minds Life Sciences Ltd. on 2024-12-01, Borealis Biosciences on 2024-12-19, and Phoenix Health on 2025-03-13), followed by another concentration through late 2025 (e.g., Feroot Security on 2025-11-20 and Cove Soda on 2025-11-05).
Which city shows the strongest repeated presence, based on the rounds listed?
Toronto appears repeatedly across the table, including Feroot Security ($14M on 2025-11-20), Reunion Neuroscience ($133M on 2025-09-21), Eli ($12M on 2025-06-10), Raenest ($11M on 2025-02-11), and Walnut Insurance ($3M on 2024-08-08), indicating a consistent Ontario tilt compared with single-occurrence locations like Halifax or Sidney.
How often are round sizes not disclosed, and does that affect interpretation of the top and bottom?
Five of the 50 rows are explicitly “undisclosed” (for example, Fairgrounds on 2025-10-12 and Velixo on 2025-04-02), so comparisons of largest and smallest disclosed amounts rely only on the disclosed subset. The smallest disclosed amount is $3M, seen for Cascadia Seaweed (2024-11-21) and Growcer (2024-04-23), among others.
Are there sector groupings that recur at least three times in this Series A sample?
Yes: Biotechnology and Agriculture and Farming both recur in multiple entries (e.g., Biotechnology includes Reunion Neuroscience on 2025-09-21 and ProteinQure on 2025-05-27; Agriculture and Farming includes FREDsense on 2025-09-26 and Growcer on 2024-04-23). These repeated labels contrast with sectors that show only one or two entries in the displayed set (e.g., Blockchain and Cryptocurrency appears but not as many times as those two).
Which entries closed most recently and earliest in the displayed window?
The most recent date shown is 2025-11-20 (Feroot Security, $14M). The earliest date shown is 2024-02-22, represented by Helius ($10M) and Zūm Rails ($8M) on that same day.
