Answer:
Both the dominion of Canada and Great Bethany had first ministers and parliaments.
Step-by-step explanation:
A similarity between the dominance of Canada and Great Britain was the adoption of parliamentarism, which is a system of government in which the legislative power (parliament) provides political support (right or indirect support) to the executive branch. Thus, executive power needs the power of parliament to be constituted and also to govern. In parliamentarism, this executive power is exercised by a prime minister.
The parliamentary system is a more flexible system than the presidentialist, because in case of a political crisis, for example, the prime minister can be replaced quickly and the parliament can be overthrown, which in the case of presidentialism, the president fulfills his mandate until the end, even in cases of political crisis.
