I would say YES. The channel narrows right at the bridge so the wave will gain in height.
It could even gain more height if the current is flowing out of the Gorge at the same time as a strong westerly is blowing creating the perfect mess.
Boaters who have encountered a "standing wave" in Baynes Channel when the wind opposes the direction of the current, will understand this principal*.
*But heck, it's just a guess
Previous tsunamis of the kind that is expected here will fill to overflowing any channel they can travel up or area they can overflow. A large wave or surge entering Victoria harbour will definitely travel as far up the Gorge as its height, the depth of the Gorge, the height of adjoining areas, and the time before it recedes will allow. Based on what we are told is the likely strength of the next Cascadia quake, a probable mega-thrust quake, I would expect the entire area to flooded as far up as Portage Inlet and beyond to an unknown depth Probably the surge as it is forced up the deep, narrow area below the Tillicum Road bridge will take out that bridge and the Craigflower Bridge and then disperse itself over the Portage Inlet "flood plain" as we could call it. I'd expect that the outflow into Esquimalt harbour via the Portage Park area will cut a channel there that will finally give Portage Inlet better drainage and fewer smells!
Just heard a biggish thump went outside thought the hooligans were up to it, dog wouldn't let me sleep after that took about 10 biscuits to calm him down.
Pay attention to the dogs. When the big one is coming they will start acting strangely in large numbers. If I hear the dogs around my place start howling and barking at the same time, which is not something they ever do now, I will take it as certainty that something big is going to happen very soon. Take a look at the videos on youtube of dogs acting up before the big Sumatra quake and tsunami.
The City publishes a seismic vulnerability map which shows soil liquefaction risk areas etc. For those concerned it's worth looking at.
