The salary questions usually get asked over in one of the forums in http://www.eng-tips.com/threadcategory.cfm?lev2=88.

That said, unless you're lucky enough to get someone in the industry, in the location, to answer you'll get limited useful feedback.

You can look at Salary.com to get a feeler but general opinion seems to be that they aren't particularly accurate.  I've seen quite a few that seem high.

The other way to look at it is, what do you need to live there in the 'manner to which you've become accustomed' + a little bit for the hassle of moving?

I don't know what the other provincial associations are like but APEGGA does salary reviews every year, check with your board website to see what they have.  You could check Alberta but obviously the values would be different due to location, from what I've heard it's higher here for most areas.
