[Paddlewise] Tidal flow for west coast of Canada

I've heard from one paddler that in addition to the local tidal currents that
flow into and out of the various bays and inlets on the west coast of Canada
(I'm mainly interested in Vancouver island), there is also a general tidal flow
that runs north and south along the entire coastline.  Given the "diagonal"
alignment of Vanc isl (i.e. running from a southeast to northwest orientation),
I'm guessing that the large tidal swell off the coast probably pushes water more
or less due east, which would then be diverted along the coast towards the
southwest (due to the diagonal alignment); with the opposite happening as the
tides pull back -- but that's purely my own speculation.  In actual experience,
I haven't noticed much of an effect.  Does anyone have more definitive
information (or links) that would explain this further?
