NF_ 10.31 Fidelity Series Canada Fund_ PRO-01 | Fidelity Series Canada Fund

Fund Summary

Fund:
Fidelity® Series Canada Fund

Investment Objective

The fund seeks growth of capital over the long term.

Fee Table

The following table describes the fees and expenses that may be incurred when you buy and hold shares of the fund.

Shareholder fees

Shareholder Fees {- Fidelity Series Canada Fund}	NF_ 10.31 Fidelity Series Canada Fund_ PRO-01 Fidelity Series Canada Fund USD ($)
(fees paid directly from your investment)	none

Annual Operating Expenses

(expenses that you pay each year as a % of the value of your investment)

Annual Operating Expenses {- Fidelity Series Canada Fund}	NF_ 10.31 Fidelity Series Canada Fund_ PRO-01 Fidelity Series Canada Fund Fidelity Series Canada Fund
Management fee	none
Distribution and/or Service (12b-1) fees	none
Other expenses	none	[1]
Total annual operating expenses	none

This example helps compare the cost of investing in the fund with the cost of investing in other funds.

Let's say, hypothetically, that the annual return for shares of the fund is 5% and that your shareholder fees and the annual operating expenses for shares of the fund are exactly as described in the fee table. This example illustrates the effect of fees and expenses, but is not meant to suggest actual or expected fees and expenses or returns, all of which may vary. For every $10,000 you invested, here's how much you would pay in total expenses if you sell all of your shares at the end of each time period indicated:

Hold Shares

Expense Example, No Redemption {- Fidelity Series Canada Fund}	NF_ 10.31 Fidelity Series Canada Fund_ PRO-01 Fidelity Series Canada Fund Fidelity Series Canada Fund USD ($)
1 Year	none
3 Years	none

Portfolio Turnover

The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual operating expenses or in the example, affect the fund's performance.

Principal Investment Strategies

• Normally investing at least 80% of assets in securities of Canadian issuers and other investments that are tied economically to Canada.

• Potentially investing in securities of U.S. issuers.

• Normally investing primarily in common stocks.

• Investing up to 35% of total assets in any industry that accounts for more than 20% of the Canadian market.

• Using fundamental analysis of factors such as each issuer's financial condition and industry position, as well as market and economic conditions, to select investments.

Principal Investment Risks

• Stock Market Volatility. Stock markets are volatile and can decline significantly in response to adverse issuer, political, regulatory, market, or economic developments. Different parts of the market, including different market sectors, and different types of securities can react differently to these developments.

• Foreign Exposure. Foreign markets can be more volatile than the U.S. market due to increased risks of adverse issuer, political, regulatory, market, or economic developments and can perform differently from the U.S. market. Foreign exchange rates also can be extremely volatile.

• Geographic Concentration in Canada. Because the fund concentrates its investments in Canada, the fund's performance is expected to be closely tied to social, political, and economic conditions within Canada and to be more volatile than the performance of more geographically diversified funds. In addition, because the fund may invest a significant percentage of assets in certain industries, the fund's performance could be affected to the extent that the particular industry or industries in which the fund invests are sensitive to adverse social, political, economic, currency, or regulatory developments.

• Issuer-Specific Changes. The value of an individual security or particular type of security can be more volatile than, and can perform differently from, the market as a whole.

An investment in the fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. You could lose money by investing in the fund.

Performance

Performance history will be available for the fund after the fund has been in operation for one calendar year.

[1] Based on estimated amounts for the current fiscal year.
