Here's an example that's put together every year by urban planner Andy Yan, a demographer with Bing Thom Architects. These maps are based on annual B.C. Assessment (tax) values for single family properties (does not include condominiums or townhomes). It is worth noting these values are calculated on an annual basis - and in a fast-paced market, the data can be misleading (2015 values were assessed in July 2014).
Also, it is very rare that "assessment value" = "market value". Typically (especially in the current detached market) market value can be significantly higher than assessment value. In 2015, you can assume most of the "Below $1 million" values on the map have now exceeded the $1 million mark. Those that remain are likely "tear down" homes and/or vastly irregular or small lots.
Despite the difficulty in capturing a moment in time for market value, these maps do provide a relative idea of values, particularly neighbourhood vs. neighbourhood, and it is interesting to see the evolution over time.
I hope this is helpful! Happy to discuss further should you have any questions.
