Greetz to all and Happy New Year!

I am in the process of emigrating from London to Calgary but I've hit a sticking point on Salary. They have offered CAD 90,000. This is significantly less (CAD70,000 less) than what I was on over here. I'm still very tempted by the offer as they are doing all the work permit & relocation stuff but I'm interested in people's opinion on this. I'm a single male in my forties with no ties here in London.

Should I go for it? I'm 80% convinced I should but the whole salary drop is worrying!

Thanks for any input.
