FREE-SHARES.INFO Free Share Profits and Free Forex Earnings

Basically i don't want to pay tax on my forex earnings, i pay enough in my regular job. I live in canada and trade forex using a UK based regulated platform. I have Citizenship in Canada and Ireland and have active bank accounts in both countries. Because I live outside of Ireland for More than 183 days I do not need to pay income tax in Ireland, so if I when I want to withdraw money from my trading account i have it transfered directly to my irish bank account i can keep it here earning interest and not subject to any tax. Is it true Forex trading brokers (such as FXCM which is the platform I use) will not disclose account details to gov agencies? Therefore If Canadian revenue does not know I have made this money and the money I have in Ireland is tax free.

Thanks to anyone who has info on this subject
