RE:RE:RE:RE:RE:RE:RE:DGof course the bank says you can sell and buy as much as you want...but its the CRA that you have to worry about. If some worker there decides that your using your TFSA as a business account then you will be taxed on all profits regardless of when you cash out. there really is no law on the books but more like a smell test.
Just goggle TFSA being used a business - and your find a few people who got burned. why even take a chance ? oh yeah - you need the money to buy a TV. You should only put money in shares after you already own everything you want and then play with whats left over - see thats me giving you unwanted advice - kinda like you do countless times everyday...
If you really wanna swing trade daily/weekly do some research and find a stock with a greater " Beta " it will be way easier and you wouldn't have to risk losing a bunch if/when the big torch order hits us - either way good luck and please cut back with daily updates of your trades all in hindsite..
