The Top of the government is the Monarch. Her position was inherited and government of Great Britain makes all final decisions. She doesn't care about BNA. That is why the colonial government was not democratic.
The governor was under the queen. This position was also inherited, and can veto any bills. The queen chose him, and she put Britain's wishes first!! That is another reason of the colonial government being not democratic.
The legislative council and the executive council were under the governor. Members were the elite chosen by the governor. They could advise the governor and decides what bills should become laws. That is again, why it's not democratic.
The legislative assembly was under the legislative council and the executive council. It is voted by voters. And they could suggest bills but they could be voted if they were against British interests. That is why it's democratic.
The voters were under the legislative assembly. Only the man who is 21 or more could vote. Also First Nations and Black Colonists couldn't vote. That is why it's kind of democratic, and also kind of not democratic.
Overall, I think it was not democratic because the queen and the governor are completely "not democratic", and Britains always had priority. Also, woman, First Nations, and Black Colonists couldn't vote. So, I think it was not democratic.
