The biggest issue is that young generations have less disposable money and this is because our governments have put us in deep debt while they continue to "steal" from the population with ever increasing taxes and services. Quebec has been living above its means for the past 40-years.
The good thing, you can pick up some very nice properties if things turn sour.
