We place turf on an open fire, like with any other domestic fuel.
Turf on it's own doesn't produce great heat - so coal and timber is also used, the turf and other fuel together then produce a long lasting and warm fire.
I think you have peatlands in Canada, any comercial and/or domestic use made of them?
We use wood in two air tight wood stoves to heat our house, but most people use natural gas, oil, or propane.
