Oops. Ok, so I am the source of the 'tax advantageous' quote. As my lawyer said "way to go Einstein"
I'll probably be responsible for every 35 year old Rob Baillie getting audited this year.
That being said, as far as I know, ATM transactions are not tracked. Your Neteller would show withdrawals but not where they occured (if you used your debit card).
Also, since the 'gaming events' occur outside Canada are you even earning the money in Canada? Does this make a difference?
If you invest offshore and spend the profit offshore you don't owe tax on it. So if you spent all your Neteller cash outside Canada I don't think you have a tax obligation.
