There are many opportunities to serve the Lord on the mission field on a short term basis. A wide range of opportunities to serve alongside assembly missionaries are listed on CMML's website and on MSC Canada's website, and these are updated regularly (follow the links below).
Note for Hillview members:
Although the MSC website says that these opportunities are only available to Canadian residents, the Hillview leadership has personal contacts with many of these missionaries. Please talk to someone in Hillview's leadership if you want to know more.
*Short term = trips less than 14 months
