This account is more useful than RRSP for anyone that hasn't bought a home yet, since it seems that contributions are tax-deductible (like RRSP), and qualified withdrawals don't get taxed either.
The money can also be transfered to an RRSP tax free, so there's no downside to doing it.
Even weirder, you can give your spouse money to fill their account without it being attributed to you, so now unevenly matched couples can fill both the TFSA and the FHSA account with no attribution.
