there is no SEWAGE PROBLEM problem in there. There is unproven rumor of radon gas . Evey time somebody ask a house in Morgan Gran. Some body would post radon gas which only a rumor and not limited to Morgan gran, all the house built on rock would has increased risk of radon gas which is fixeable.
In every city there would be some area cheaper than another. In kanata, kanata lake is most expensive, because of the golf course(more rich people there) and close to central and high way. at north morgans gran and at south bridlewood are cheaper than Kanata lake. It is still a good area to live. If it provide better value for money, why not.
