It's family size at the time of application.
So you need to take your current family size including your parents - and then have to meet LICO for that family size for 2013, 2014 and 2015 to apply in 2017.
scylla,
i really doubt on that note, expecting the family count as of today(applying date) for last 3 years, expecting for the future income is possible
example, i am single, i am pgp2016
2012 - i am single, so my family size is myself + dad+mom = 3
2013 - i am single, so my family size is myself + dad+mom = 3
2014 - i am single, so my family size is myself + dad+mom = 3
Now my application is in process and if for next 2 years it takes to process, then CIC asks
2015 - i am single, so my family size is myself + dad+mom = 3
2016 - i am single, so my family size is myself + dad+mom = 3
2017 - if i am married, then my family is 4, then my income category should meet 4 for 2017, and its practical that my spouse supports me on the income, which can meet the LICO table
2018 - i got twins, then it becomes 6
2019 - CIC asks for income proof, so for 2018, i should meet the income category 6,
NOT for all the years from 2012
and this same logic should apply at the time of applying in 2016
'NOT' was missed
