Your tax period for Canada begins in June, so those dividends wouldn't apply. Assuming this is a taxable account (rather than, say, an IRA), you'll want to make note of the valuation of your stocks & bonds as of the time you moved, as these will become the new cost basis for Canada when you eventually sell them and declare capital gains. You should also note the US dollar - Canadian dollar exchange rate for that time, as your cost basis will be in terms of C$.
