Again, we're working with data identical to that of Finance Canada, which they offered in their testimony to the committee last week. That's the 2013 CRA data.
By income group, you roughly see that individuals who filed T1 returns and who claimed that they had a total income of $45,000 or less, on average maxed out their TFSAs at a rate of around 15% overall. The rate for individuals who were claiming higher income on their T1 returns, above $45,000 per year, was roughly 19% to 20% overall.
So, of one in five Canadians who had a TFSA in 2013 and who reported income of more than $45,000 a year, roughly one in five of those was maximizing their TFSA.
