TFSA - how much to invest vs how much to keep in GIC

Husband and I both have our TFSA and FHSAs fully maxed out.
We have been keeping everything in GICs at EQ bank, incase we buy a home, but it’s been almost 7 years now and looking at the numbers i don’t think it makes financial sense to buy (in the lower mainland).
Husband accidentally transferred his entire TFSA balance from EQ to WealthSimple (plan was to transfer 30k to invest in XEQT), but now I’m thinking maybe we should invest a larger amount (maybe half of it) into XEQT?
If we each invest half of our TFSAs into XEQT, that will leave us with roughly $60k each in GICs, plus our FHSAs if we decide to buy.
Any thoughts or advice? I’m feeling a bit hesitant to invest such a large amount of our TFSA in the market.
Both our RRSPs (40k & 75k) are invested in XEQT, but since retirement isn’t for another 35 years, I’m not worried about it. Thank you!
