Well, the Leafs still have their 2027 1st rnd pick to Philli which is top 10 protected according to the NHL.
Top 5 protected, slides to 2027. The 2027 pick goes to Philadelphia (as part of Laughton trade) if it is outside the top 10, which converts this pick to Boston to a 2028 unprotected 1st Round Pick. If this Pick slides to 2027 and is in the top 10, TOR can either transfer it to BOS to satisfy this trade and then give PHI the 2028 unprotected, or transfer it to PHI and give BOS the 2028 unprotected 1st Round Pick.
