For anybody curious about an approximate price for remediation, I paid $2600 to Radon Controls Inc in June 2020. They cut through the basement wall to outside, bored a concrete hole through the floor, shoved some sort of pipe (maybe ~5" diameter) into the ground underneath the house, attached an inline fan and it continuously exhausts outside. They did a couple other little things, but that was the total cost. Brought us from borderline over the limit in Canada -- and well over the limit the EU suggests -- to basically nothing.
