there's little point in comparing other markets...my colleague in Edmonton makes around 25% more than I do and claims winters aren't even that bad haha

sounds like you have the right idea...if they can close to gap to say 10-15% of the competitor offer, I would stay. Job satisfaction is more important if you already have stability.

How likely is it that they'll bump you 15% though? Is there a way to find out if the competitor's offer isn't just smoke and mirrors? They might just trying to make things sound enticing, and when you jump ships you find out you're actually worse off in vacation time, benefits, etc.
