<prompt> Human: I am looking at building up an emergency reserve and being in Canada I was going to keep it in a TFSA. However, now that nearly everywhere accepts credit card and I have access to a LOC with more funds than I would keep as an emergency fund, whats the point? It would only take 30 days to withdraw from investments without penalty to pay off my credit card or LOC should it come to that.Everyone says you should have 3 months reserve but Id rather keep that cash invested. Thoughts?  <response>: Lines of credit can and do get pulled at any time, due to any reason. I would not count on it being there.
