I don't think I can comment on the rural areas. I think in some of the studies I have seen, there is a breakdown by large census metropolitan areas, or CMAs, and other areas, so maybe that could inform you.
In terms of certain economic sectors, pulling up some numbers today from our CANSIM tables, we have hourly wage rates in 1997 compared to 2015. You were commenting on the forestry, fishing, mining, and oil and gas resource. Here we see that in 1997 women earned 83¢ for every dollar earned by men, and by 2015 it had gone up to 92¢ in that particular sector, so that was a gain of 8.2 percentage points.
We also saw large gains in the construction sector. I think that construction was up almost 10 percentage points. These are just unadjusted gaps, unadjusted for anything; they are just raw gaps. These types of numbers are readily available from our labour force survey that's on CANSIM.
