Certainly not all that construction is related to real-estate. Still real-estate as a % of GDP eclipses "mining, Oil & Gas".

I'm pretty confident that someone who, according to that chart, is in the "real estate" industry who works selling houses in newly-built mining towns knows full well what industry really supplies his income.
A very brief search resulted in this:

If that's accurate, it suggests that Manitoba, which, though known as more agricultural and manufacturing rather than mining, has the same pattern of "real estate" accounting for individual income. Of course, the significant majority of the population is in Winnipeg, but I don't think that qualifies it as a major, on the same scale as Vancouver or Toronto.
Again, I think that even real estate "industry" workers in Winnipeg know their money really comes from manufacturing, just as the ones in Edmonton know their money really comes from oil.
Maybe in the major cities you mention it's not so obvious, but "real estate" still fails to eclipse the sum of all the industries that actually produce something (manufacturing, resource extraction, construction).
If resisdential RE tanks in Canada, a real possibility with rising interests rate and extreme debt levels, the economy goes down with it.
Mining / Oil & Gas isn’t going to save it.
(Those charts also fail to show how much of that income is from residential transactions/management versus commercial ones.)
It just doesn't stand to reason that if people entirely stop paying other people to buy and sell each other houses (even if it does account for the vast majority of that 13% of the GDP) that the economy would collapse completely.
However, if housing values collapse due to questionable (or worse) lending practices, as happened in the US around 2008, could collapse the financial system and thereby the economy. It might even increase the GDP of the real estate category, especially as a percentage, at the expense of the finance category.
More importantly, though, I don't think there are any voters that buy the notion that they could, for example, do away with their real industry, such as mining or manufacturing, and replace it entirely with selling each other their houses. Because of that, whatever conservatism they may hold would remain from that real industry, regardless of what category the statisticians put their income in.
