However, this does not adjust for free healthcare and education.
On the other hand, tech cost of living is skewed by SF and Vancouver.
SF is the #1 tech city in the US whereas Vancouver may be #2 in Canada, but the US is a larger country so SF may "dilute" more. Without stats, this is just guesswork.
And if you happen to join a great tech company, chances are the health insurance you'll get is superior to the general public healthcare system in Canada.
The major economic tech centres in Canada are Toronto and less so, Vancouver. Montreal and Ottawa (because that's where Shopify is HQ'd) are the next biggest.
Toronto and Vancouver are hugely unaffordable when it comes to housing; Montreal and Ottawa are much more affordable.
I have two kids. I get offers between 100k/160k CAD in Montreal. Daycare costs me about 800$ per month for each children and I get kick backs from the governement to bring that down to roughly 189$CAD/month. In San Francisco the average is 1900$USD per child.
Then factor in I live in a 265K CAD house, 40 minutes bus ride to city center. I have 3 bedrooms, one office, a huge kitchen, a nice patio, garden etc... In San Francisco the median house price is 1,194,300$ USD.
I could be making 180kUSD and I wouldn't be saving any more money at the end of every month with housing and daycare alone.
Also... I might pay a good deal of taxes but I have great healthcare.
