I'm looking for third party 4 bolt Shimano road pattern chainrings.
Simple reason, for youth gearing limits, a parent would have to change the gearing once or twice (every 2 years), and the price of original Shimano Chainrings is prohibitive for a short investment.
So, any known brands ?
Spécialités TA aren't available in Canada :(

FSA ABS ring works for the shimano asymmetric bolt pattern. Blackspire also make some compatible chainring in their superpro line. If you are looking for a 44 or 46 though that one is a lot harder to find.

Are you sure about that? It looks pretty different to me.

What chainset? 6800 and 8000 are different, have you looked at strong light?

Easton makes a bunch of smaller chainring sizes and they use the shimano 4 bolt pattern.

What about just going 39t 1x and an appropriate cassette like 11-32t.

Are the wheels 700c?

Miche and stronglight make these. Carbon Ti do too. Be aware the new R9100/R8000/R7000 outer ring are different to the older 4 bolt rings.
