How do you all think about “runway” if your income suddenly stopped?

With all the layoff news lately, I’ve been thinking more seriously about how long I could realistically last if my income stopped for a while. I know my savings and my monthly spending, but I’ve never really thought about how people actually calculate their “runway” or plan for that kind of uncertainty.

I’m not asking for advice on my specific situation, more just curious how others approach it. Do you think in terms of months of expenses? A certain emergency fund size? Cutting certain categories first? Or something else entirely?

Trying to understand how people in Canada think about this from a planning perspective.
