Abstract
We extend the proof of automatic continuity for homeomorphism groups of manifolds to non-compact manifolds and manifolds with marked points and their mapping class groups. Specifically, we show that, for any manifold homeomorphic to the interior of a compact manifold, and a set homeomorphic to the union of a Cantor set and finite set, the relative homeomorphism group and the mapping class group have the property that any homomorphism from such a group to any separable topological group is necessarily continuous.
