There's also a problem with liquefaction. Most of Victoria and Vancouver (in BC) are built on soft earth which will become mud and will stop supporting the stuff we've built. All those foundations, bridges, streets, they'll all become impassable. There's a liquefaction map I saw at an engineering presentation and the whole thing was red and black. Victoria is literally built on landfill garbage right next to the ocean. One of its landmark buildings, the Empress Hotel, was slowly sinking until it had a major refurb to drive piles down as far as they could reach.
Vancouver is the biggest port for exporting all of Canada's wheat, lumber, ore, etc. If it shuts down, people could be starving for work and food all over the world. It's not all bad though, because EA North would cease to exist. However, greater Vancouver is where most of BC's engineers live and work. We're your experts in fixing up after an earthquake, and most of us would probably be gone.
It's going to be bad when it hits. The upside is that most people here have earthquake kits, emergency supplies, ninja reflexes (we do earthquake drills) and have some idea that it will in fact happen.
