Interesting patterns
Things that stood out in the data
Nortel alone accounts for ~$700B. The dot-com trio (Nortel + JDS + 360networks) represents over $1T in lost peak value — nearly half the ecosystem's all-time total.
Of the 3 bootstrapped unicorns, 3 have survived as independent entities. 100% survival vs. ~65% for VC-backed.
Of Ottawa's 27 unicorns, 13 are now acquired, defunct, or PE-owned. Only 14 remain independent — a stark contrast to Toronto.
Canada's most successful serial acquirer is now valued at over $112.0B CAD, larger than BlackBerry ever was at its peak.
38 of 118 unicorns are headquartered in the GTA — more than Ottawa, Waterloo, Montreal, and Vancouver combined.
89 of 118 unicorns achieved their valuation in the 2020s — a massive acceleration in ecosystem maturity.
Acquisitions: where they went
Destination of the 20 acquired unicorns
