Horseshoe Bay is one of the two main terminals for the ferry across to Vancouver Island. The Trans-Canada Highway ends up right in the assembly area for the ferry so its a significant point (see here on Flashearth; you can see how it got its name of Horseshoe Bay). As well as serving Vancouver Island, there are several other smaller islands connecting by ferry to Horseshoe Bay.

Although this scene looks peaceful enough, 5 years ago, a ferry deliberately missed the docking area and smashed its way through the marina seen here to end up beaching itself. There was a problem disengaging the propulsion and rather than smash headlong into the dock, the Captain had the presence of mind to take a less-damaging option of beaching it. This has the story; it is worth reading.
