Shale gas is being promoted in the province of Québec as an Eldorado that will end dependency on Alberta oil from tar sands. I expect that it will extend to Ontario as soon as companies get their exploration licences for prospecting gas deposits in your back yard.

Maybe not an Eldorado, but in one of my gas/oil journals they list the drilling projects in North America - naturally Texas is numero uno, the, of all places, North Dakota is #2.
The ND formation also reaches into Manitoba where considerable drilling is starting. Out of (say) ten drilling sites in the world now. (Poland among others has large shale deposits) I would say that 6 are in shale oil/gas fields.
There is a broad depost of shale in the northern mid-western states and another that stretches through Ohio, east through NY state (espcecially in the NYC watershed

) and up into Quebec. Frack them all .... the gas/oil/condensate is trapped inside the rock formations and by pumping HP water into them, say, at 12,000psi, the rock is FRACTURED and the hydrocarbon is set free.
I did a lot of work with a small company in Alberta named FRACKMASTER that specialized in that (it is useful in extending the life of dry producing wells) - it was later taken over by Cheney's Halliburton - who made life wretched for the workers.
Remember that for the last ten years more oil has been pumped out of the ground than has been found. Petrobas, the Brazilian oil company has just found a field off shore with 10 billion barrels (estimate) and that will bring up the numbers.
Alberta has been pumping out more oil than finding since 1972.
