You wouldn't see the destruction that are seen in various countries. tsunamis would not be able to generate in the straight as it is too small to gain steam. If a major earthquake was to hit the most damage would occur on the west coast of the island which is open to all the pacific but even then we have warning systems for that.
Don't let earthquakes scare you. This is just the way of the earth to maintain its shape like when we burp we are releasing built up air or we start to feel the pressure build. Its just relieving the pressure to make it more comfortable.
Even though some people say earthquakes are becoming more frequent they really arn't. They have maintained steady over the last 100 years
On any given year we usually get 1-2 8.0 or higher. a couple dozen 7.0-7.9. And thousands of anything below that.
It also really depends on the nature of the quake, this one was quite large for interplate or intraplate earthquake. The really big ones are the subduction zone ones, and you can't get one of those in Vancouver ... however Victoria would be pretty screwed ...
This one was somewhat shallow at 10 miles, but the ugly ones are when you get surface rupture in a populated area ....
