Conferences in the United Church of Canada are courts of the Church organized as an administrative grouping of Presbyteries in a geographical area. The Conference is governed by a body consisting of ministers within its boundaries and an equal number of non-ministerial representatives of Pastoral Charges. Functions of a Conference include the following: determining boundaries and numbers of Presbyteries within its bounds; receiving and disposing of appeals and petitions subject to the usual right to appeal; sustaining pastorate in every Pastoral Charge; examining and ordaining candidates for the Order of Ministry; receiving ministers and deaconesses from other Churches; selecting equal numbers of members of the Order of Ministry and lay representatives to the General Council.

Upon its constitution in 1925 the London Conference encompassed the Elgin, Essex, Huron, Kent, Lambton, Middlesex, Oxford and Perth Presbyteries. Algoma Presbytery came within its jurisdiction in 1941. In 1968, Huron and Perth Presbyteries amalgamated to form Huron-Perth Presbytery.

On January 1, 2019, London Conference disbanded and the congregations within its boundaries became part of the following Regional Councils: Canadian Shield Regional Council, Antler River Watershed Regional Council and Western Ontario Waterways Regional Council.
