there is no hard fast rule for amount of trades. The CRA breaks down stocks into two categories, trading and investing. It sounds stupid in similarity however make a big difference.
I personally bought ACB at $2.15, $2.50, $4, then a large contribution to max out my TFSA at $7. In the whole time i have only sold and bought my position once (at a loss no less). Ergo, I shouldn't be audited. .
I haven't heard a case of refreshing or research to be a cause of audit although it wouldn't surprise me. From my understanding CRA looks for people in the finance industry who trade within the TFSA for the tax advantage. In these cases the gains have all been taxed as business income. In which case you could be seeing over half your gains go to the tax man.
In summary, staying long in your TFSA and trade in your cash account is the "right" way to do it but doesn't guarantee you won't get audited.
