Extraction is quite a bit different.
Is it more difficult and/or expensive than the deposits in Canada?

For the oil shale, typically they drill down, inject steam to liberate the oil from the rock and them pump the oil out.
The oil sands are mined with huge surface mining equipmnet to a central facility for thermal extraction.
That is my undertanding, I may not be 100% right, but I have studied these some.

This is typical of deep deposit extraction, whether it's oil trapped in sands or shales.
This is from the Athabasca Oil sands deposti site where the deposit can be reached from the surface:
