Ching was left exposed by Houston in the 2011 MLS Expansion Draft and was selected by expansion side Montreal Impact less than a week after playing in the MLS Cup final. Ching was traded back to Houston on February 16, 2012, for a first-round draft pick in the 2013 MLS SuperDraft, after training with Montreal for about a month, coincidentally playing a pre-season game against the Houston Dynamo.
