I'm writing from Canada. Mother and/or father can share up to 35 weeks of paid leave under the national insurance program. This maxes out at, I think, approx $500 per week. It's not a lot. But it helps.
Regarding societal values, this the same program that would normally pay you temporarily if you were laid off (not by choice). Normally you wouldn't be eligible to collect benefits if you willingly left a job. Pregnancy is generally considered to be a choice, so I think making these benefits available to parents shows society does value the choice to parent and will subsidize it.
Parents who adopt a child receive significant additional benefits on top of the standard allowance.
Recently there have been changes to the program to improve benefits for self-employed. As we on HN know ... sometimes a startup founder isn't "employed" or receiving salary in the usual sense and historically it was difficult for such professionals to receive employment insurance benefits but it's changing.
Anyways, progress? :-)
