Final answer:
Canada has adopted the Senate system from Ancient Rome, where the Senate played a pivotal role in government, whereas Canada's Senate is part of its parliamentary system.
Step-by-step explanation:
Canada has adopted the Senate system from Ancient Rome. In Ancient Rome's political system, the Senate played an integral role within the government, existing throughout various stages of Rome's development from a kingdom, to a republic, and finally to an empire. The Roman Senate, composed of aristocratic administrators, was responsible for controlling state finances and had significant influence in the governing process. Similarly, Canada's Senate is part of the parliamentary system, mirroring the Roman tradition of a legislative body. Unlike Ancient Rome, Canada's government is a constitutional monarchy that incorporates the Westminster parliamentary system, blending its unique historical context with aspects of Roman governance.
