You need it to dig deeper. I have a pension which I can get at 65.

I have options to collect social security. What if I draw my 401k first and wait until 72 to start as? Or I can get take as at 62 and the 401k grows more...

Edit point is you need an account to start asking those questions.

The timing half is there: CPP/OAS or Social Security start ages, and pension start and end ages, so claiming at 62 versus deferring is something you can run both ways today.

Draw order across accounts isn't exposed yet. Right now the engine allocates by equalizing marginal tax rates across accounts each year rather than draining one at a time, so it's solving that ordering instead of letting you set it. The manual override is a fair ask and it's coming, the engine already takes the order as a parameter and it just isn't wired to the UI.

yeah, this is quite literally the first thing i saw when i opened the page.
