From 1926 to 1937, the pastor was Fr.

In 2007, Assumption Church added to its schedule the celebration of the Tridentine Latin Mass on Sundays at 2:00 p.m. The church's high altar, sanctuary, communion rail, and pipe organ make it well-suited to this type of liturgy, which attracts churchgoers from throughout southern Ontario and southeastern Michigan.
Assumption's Latin Mass Community hosts regular special events, and the Latin Mass Choir is regularly called upon to sing at special Latin Masses throughout the region.

In 2007, it was learned that Assumption church needed C$9.8 million in extensive restoration repairs.
In 2012, a re-assessment of repair costs saw this amount rise to approximately C$15 million.

Assumption Church was closed in November 2014 after the building's condition deteriorated.
Worship continued daily in the Rosary Chapel and on weekends at the former Holy Name of Mary Church.
The Roman Catholic Diocese of London has stated its commitment to the church's restoration and reopening if a donor comes forward.

In 2017, Assumption parishioners began hosting a series of events to celebrate the parish's 250th year.

In early 2019, local lawyer Paul Mullins spearheaded a fundraising campaign and four-phase restoration plan for the church building.

Construction began in the spring of 2019 on the first phase.
 Work included the installation of a long-term copper roof, a new heating system, major electrical work, and structural repairs.

The parish moved back into the church on September 8th, 2019 and began celebrating weekend masses there again.

The parish is preparing to launch the second phase of the restoration plan in 2020.
 The second phase includes restoration of the church's ceiling.
