Share of occupied homes, by the era they were built in. Bars are drawn against the busiest era, not against each other, because the eras are not the same length. The eight shares are unlikely to total exactly 100: Statistics Canada rounds each era's count to the nearest 5 before publishing it, so we print what the census reports rather than adjusting a figure to make the column add up.

28 of these months closed fewer than 5 sales. A middle value taken over that few is not a market figure — with one sale it is simply that home's closing price — so the count is shown and the median is not. The sales themselves still count toward the 12-month figures above.
