I dont have access to the latest data or research regarding the compressive strength of Canada Champagne Limestone. However, it is common for the compressive strength of limestone to range from 30 MPa to 250 MPa, depending on the specific type of limestone and its geological properties. It is best to consult with a geologist or a professional in the building and construction industry for the most accurate information on the compressive strength of Canada Champagne Limestone.
