Any individual who is 18 years of age or older and who has a valid Canadian social insurance number (SIN) is eligible to open a TFSA.
You cannot open a TFSA or contribute to one until you turn 18. However, when you turn 18, you will be able to contribute up to the full TFSA dollar limit for that year.
Example
Julie turns 18 on May 13, 2012. She will not be able to open and contribute to a TFSA until that date. However, as of May 13, 2012, she can open a TFSA and contribute the full 2012 dollar limit of $5,000.
Note
In certain provinces and territories, the legal age (depends on the age of majority) at which an individual can enter into a contract (which includes opening a TFSA) is 19. In 2009 or later, in these jurisdictions, an 18-year-old who would otherwise be eligible accumulates $5,000 contribution room for that year and carries it over to the following year.
The account holder is the only person who can contribute to their TFSA. You can give your spouse or common-law partner money to contribute to their own TFSA without either that amount or any earnings on the amount being attributed back to you. The total of all contributions your spouse or common-law partner makes to their TFSA must not be more than their TFSA contribution room.
You may be considered a non-resident for tax purposes if you:
Even if you no longer live in Canada, you may have residential ties in Canada that are sufficient for you to be considered a factual or deemed resident of Canada. In these cases, the regular rules for opening a TFSA still apply.
Residential ties include:
Other ties that may be relevant include:

If you become a non-resident of Canada, or are considered to be a non-resident for income tax purposes:
You can contribute to a TFSA up to the date that you become a non-resident of Canada. The TFSA dollar limit (for example $5,000 in 2012) is not pro-rated in the year of emigration or immigration.
If you make a contribution, except for a qualifying transfer or an exempt contribution, while you are a non-resident, you will be subject to a 1% tax for each month the contribution stays in the account. You may also be subject to other taxes. For more information, see Tax payable on non-resident contributions.
