Southwest Airlines does not have a physical office in Vancouver, BC, because they do not fly to Canada, primarily due to their payment system not being set up for Canadian dollars. While you can't fly Southwest directly to Vancouver (YVR) or find a local office, you can use their partners or book flights to nearby US cities and drive across, but you'll likely find better options on airlines like Air Canada or other US carriers that serve Vancouver directly.
