If i earn money online (from my own website) do I need to claim it on my tax report (I’m in Canada)? ‘Cause if I don’t claim it, there’s no way for them to find out how much (if any) I earned, right?

i need to send money online from canada to australia – i have a feeling that paypal is going to charge me a couple of limbs just to do it. anyone know of another SECURE service that does this, with a small fee?
