TFSA frequent trading
I read today that the CRA is auditing tfsa accounts. The criteria to define a tfsa that operates as a business are quit gray. Do you know anyone who was ever audited? how would the tax be applied ? I mean let's say you has 5 k in your account. Than you made it to 30 K on one stock, moved money to a different stock and ended up losing everything. Would you still owe tax money on the 25 k you made initially ? I am new to investing and was curious on how the whole system works.
