Based on all current scientific knowledge, the wind turbine will cause no adverse health effects, and it will be inaudible to 99.99% of the neighborhood. Making a huge issue out of this will do more harm to property values than the wind turbine alone ever could.
The only thing worth disputing are the economics of the project, and I am not even sure if there are grounds for doing that. According to Saskatoon Light & Power, the project will generate 500,000 dollars annually for 20 years and cost about 5,000,000 dollars in total. They did not produce a paper describing all of the economic particulars, though, so I suppose some could oppose the project for economic reasons if they had sufficient evidence.
The group has a website set up:

I am embarassed when medical professionals weigh in on a subject they know nothing about. They are preying on people's hysteria of the unknown (invisible sound waves in the air supposedly cause X illnesses) for their own personal gain. On the subject of wind power, they are charlatans. There is a somewhat famous GP in the States who writes books on the dangers of wind power, even though there is no scientific evidence supporting her claims. This scares people.
All that said, I do wish the setback distance was a bit greater; the turbine is being placed on the edge of the landfill closest to Montgomery. Why not on the opposite edge of the landfil, which would move it 200 - 300m back? This would be more in line with international setback requirements for landfills.
Also, if one wind turbine is so profitable, I would like to see wind farms built. Building one wind turbine in this location has succeeded in riling up Saskatoon's citizens and will do little to offset the fossil fuels used by the city. It is little more than a symbol. Why aren't more wind turbines being built in a location that is rated higher than "marginal"?
