Papilio zelicaon
It is an Anise Swallowtail. The Oregon Swallowtail looks quite different (wings a bit different in shape, much more yellow, more yellow on body, dark spot mentioned on hind wing is a different shape, etc.), and may not range that far north (?). The Old World Swallowtail looks a bit different too, and the spot mentioned is more of a line in that species. In the Anise Swallowtail, that spot is quite often elongated a bit and connected to the inner edge, especially on the under side (even though some literature would have us believe not), but it is always large, rounded, and roughly centered in the orange/yellow area.

is eastern. This one is Anise Swallowtail HERE

 
Black - Not
Perhaps not Anise either, as Anise requires that the black pupil spot be centered in the orange eye spot. Consider instead "Old World Swallowtail" (Papilio machaon), either the Baird's or Oregon subspecies, both of which occur in southern British Columbia. According to Kaufman's Field Guide, p. 32, this species overlaps with Anise. One of the ways you tell them apart is that in Old World: "Hindwing eyespot with oblong black patch along lower margin, no centered pupil." That characteristic seems to be true in your photo.
