No debt, a million in the bank just quietly appreciating--these guys are DONE. The accumulation part of their lives can be over today.
Now it's just a matter of leaving the savings alone, and bringing in enough to keep their roughly $4k per month living costs (once they stop adding to savings) ticking over. (And they could even reduce those: why are transport costs $4800 per year?) Lots of options, lots of choices: freedom. Ain't Canada great?
And no, do not buy a $30k car every so many years. Never do that. Buy a good used $12k car.
In their position, I would talk to my employer about backing down to say a 60% of full-time position, now. Work 3 days per week, see how that feels. They have the option to try that or lots of other things.
