Typos! When Upper Canada was created in 1791, not 1719!
SUC 1791, c. 1
I also don’t know much about this but I did recently find and post to another thread a review of Japan’s Feudal-era Criminal Law, which was interesting to read about and might give you some sense of the transitions that were necessary:

I would imagine that a large part of the shift was getting rid of laws to do with classes (samurai, commoner, Burakumin, etc.)
In one legal opinion, I’ve cited a decision from Star Chamber, and in another, I’ve cited an English statute from the reign of Edward IV.
There was also a Supreme Court of Canada case 35 years ago that turned on the Statute of Frauds, (Eng.), 29 Car. II, c. 3, s. 4. Not a re-enactment by the province, but the English statute, which was part of the statute law of the province under the doctrine of reception of English law.

Just of personal interest: One of the very first statutes enacted by the First Congress was the Copyright Act of 1790.
