It outlines the key events and terms related to each company's operations. The HBC was established in 1670 and had a strict hierarchy and trade practices, focusing on trading goods at its bay posts. The NW Co was more flexible and established deeper in the interior by "wintering" partners. It had advantages like easier access for trappers and a vested interest structure. The document examines the differences in how each company operated and structured its trade.
