I know that the Canadian Revenue Agency (CRA) is always ambiguous about intraday trades in TFSA. For example, you just bought TD and CASH, but regretted it next week and wanted to sell them all to switch to XEQT and VFV.
Is it too soon for this buy and sell? Should I wait for a month or longer? I know they value holding period, but I'm not sure how it's defined. And I don't have much money, just a few thousand yuan. $VANGUARD S&P 500 INDEX ETF TR UNIT (VFV.CA)$ $ISHARES CORE EQUITY ETF PORTFOLIO UNITS CAD (XEQT.CA)$
