Not a lot of people can spend 1/3 of a year on vacation. I'm in Sweden and I consider my vacation time pretty generous (6 weeks per year), but still, I'm still nowhere near 1/3 of a year.
I assumed that holidays and weekends count as "vacation", in which case you are already there if you don't work on the weekends. If not, then yes it's definitely unrealistic for many.
I think he meant time off (which is more realistic) Considering most people have 2 day off each week + the statutory holidays the 1/3 is actually achievable.
(exemple for canada with 4 week off: 52*2=104 "week end" + 10 statutory holliday + 4 week (20 days) vacation= 134 days/365 = 37% more than 1/3)
