The Quebec companies are no different from the Canadian companies. I've seen all companies face the same challenges.
Remember that these companies don't make a profit, since they're start‑ups. All Canadian clean‑tech companies face major challenges in terms of funding and sales. I would say that Quebec start‑ups don't face unique challenges.
When it comes to conquering global markets, technology companies in the Halifax area face the same major challenges as companies in Vancouver or Toronto. They all face the same competition in global markets.
