all investment income (interest, dividends, trust distributions and capital gains) will accumulate tax-free
	contributions are not tax-deductible
	withdrawals are not taxable
	capital losses are not tax-deductible

	Interest on money borrowed to invest in a TFSA is not tax deductible.
	A TFSA can be used as security for a loan.
	According to bank representatives, a TFSA cannot be used to provide margin for linked margin brokerage accounts, although this is not disallowed by the Income Tax Act.
	If you wish to use your TFSA to increase your margin, you can borrow against the TFSA and put the money into your margin account.  The interest on the debt would be tax deductible.

On October 16, 2009 the Minister of Finance announced proposed amendments to the Income Tax Act to strengthen the rules applicable to Tax-Free Savings Accounts.  The proposed amendments would:

	Make income from deliberate overcontributions and prohibited investments subject to existing anti-avoidance rules in the Income Tax Act
	Make income attributable to non-qualified investments taxable at regular income tax rates.
	Ensure that withdrawals of deliberate overcontributions, prohibited investments, non-qualified investments or amounts attributable to swap transactions, or of related investment income, from a TFSA do not create additional TFSA contribution room.
	Prohibit asset transfer transactions (swap transactions) between TFSAs and other accounts.

Information on the proposed changes is included in the articles below.  It is proposed that the amendments will apply to transactions which occur after October 16, 2009.  The draft legislation and explanatory notes were released by the Department of Finance on April 30, 2010.
