Your table is conveniently lacking the salary ranges I've been offered from over a dozen higher paying companies in the city...
In fact, not a single company that pays well whom I've talked to is on your list other than Amazon and Microsoft (Whom will pay a whole lot more if you point the spread out to them).
I am planning on converting this data to website that will keep track of what tech employers are in the city. Kind of like HackerBatch but just listing companies, not delivering job postings. (Also, it will be available to the public, not just UBC/SFU students. You won't have to get 50 students from your school to sign up like with HackerBatch, either.)
For the moment, I'm protecting the sheet so I have a stable source from which to work. Stay tuned...
