Part of the bridge must be east or south of Nanaimo. It can connect us to Canada or Canada to Canada, as long as it's the island connected to the mainland. Using islands to hop is okay as long as there is a full connection.

And is this question specifically about bridges? What about an underwater tunnel? I’ve seen the phrase “fixed link” used to speak to the different types of permanent infrastructure to allow transportation.
There are no fixed bridges in existence today that would meet the conditions present in Georgia Strait.
So not impossible, but it has some pretty challenging conditions currently. And not that much economic benefit?
