I too was in your position of anxiety and puzzle when looking for house in this community. But after all the researches I could pull from all sources, I realized my worries were just overkill:
- There exists this radon gas everywhere in Ottawa, in fact, in every continent on this planet, so long there's rocks and minerals. The gas exists in rocky areas because it is released mainly from granites, marbles and such mineral stones.
- Kanata sits on a rocky segment, you can tell by looking at the excavations around the are. For that reason, people think that it may have higher concentration of radon gas. That's not true, radon gas level is house dependent, not region! just because your house has high level of radon gas does not mean that your neighbors have too!
- if radon gas concentration is too high in the area, why hasn't the city had a such case so far? I had the house have a radon gas test done before moving in, and the lab that runs the test told me that of the 20 years they've been performing the analysis, they have never seen a case where the level was above average, not a single house in the entire national capital region.
