I'm always weary of "having a moment" stories. It often means the author is going to try to string together unrelated events into a narrative.
Canada will "begin to have a moment" when a $20bn exit spawns a legion of millionaires happy to become VCs.
Except they probably wouldn't want to become VCs since they don't see many successful VCs around them, there aren't many big exits, and there isn't a huge startup ecosystem.
Chicken and egg problem.
The IVADO (a cross university data science institute in montreal) recently got a $93M investment for research and promotion of data science in Montreal.
