I've had some trouble finding closely comparable values but it seems like the median SF detached home price is ~$1 million. Even considering the exchange rate, it seems like Vancouver is more expensive.
Certainly when one compares typical incomes Vancouver is dramatically less affordable than San Francisco.
And that's CAD, not USD. In USD it's $1,092,000. Still very expensive but not $1.76mln.

Vancouver's market had a reputation of being driven by Chinese cash... and whether that's true or not, perception is reality when it comes to markets.
Here's a pretty typical example: https://www.realtor.ca/Residential/Single-Family/17409318/55...
Before you ask, no that's not even in a really desirable part of Vancouver.
That will cost you another million. See this as an example: https://www.realtor.ca/Residential/Single-Family/17850427/31...
If you mean housing cost relative to salary, however, that's perhaps a different story.
