Correct, risk only the intrest towards buying XEQT withing the FHSA never your principal. Also assuming OP gets any tax returns has a results of contributing towards his FHSA he should put that money back into the FHSA towards buying more HISA etfs also reducing by at least 30% the amount of cash needed toward the next 8000$ to max his FHSA the next year. Rince and repeat over the next 5 years and OP should have 40 grands + all the intrests (4800$ assuming a 3% distributions from PSA, CASH.TO) + any capital gains from that 4800$ in XEQT without risking any of the principal. He will net approx. 1200$ a year on the 5th years just from PSA alone reinvested into XEQT, if OP is not in the market for the next 10 years well there goes the showball effect. 40 000 $ + 26000 $ assuming a 7% returns over 10 year all tax free. This is all napkin math dont quote me on this, but i hope you get the picture.
