The introduction of Tax-Free Savings Accounts (TFSAs) in 2009 transformed how  Canadians save. One of the main reasons for creating TFSAs was to provide a taxassisted savings instrument for low-income Canadians to enable them to improve their retirement income. Now, 10 years later, many low-income savers are still not using TFSAs in ways that would allow them to benefit fully from the government transfer programs intended for them in retirement, such as the Guaranteed Income Supplement. Consequently, intended benefits from TFSAs are going untapped. Improving public education and financial literacy may be part of the solution to this problem, but built-in policy nudges and tax adjustments will be more effective.
