Are any flight schools or clubs in Canada using Pipistrel's Alpha Electro or Velis Electro? I'm interested in the business and environmental possibilities of using electric trainers for training.
Are there flight clubs or flight schools training with electric aircraft?
I thought I'd read that Canada provided some kind of type rating for the Alpha Electro, and I'm hearing that Pipistrel's newer Velis electro is certified (at least in Switzerland).
Is anyone doing this now in Canada? If not, why not? Are there regulatory obstacles?
The only Pipistrel Electro registered in Canada is an Alpha, C-IZAP, registered to a private owner in British Columbia.  So the answer is for now, no.
Pipistrels, including the Electros, are licenced in Canada as Advanced Ultralights.  I don't see any reason an Electro couldn't be used for training under the Advanced Ultralight regulations (not for Private Pilot however).  Probably cost is an obstacle.
