Too cold. Jujube needs mild winter and hot summer to fruit well.But you can grow one in pot, overwinter at garage.
You can buy one from floral exotic nursery at Montreal.
It's an insult but Ottawa is colder. Ottawa maybe similar to Harbin. Never tried in ground, tried in a pot. Fruits very well but all taken by squirrels.
