Cost effective, new antenna technology is required to build the large collecting area being planned for the next generation of radio telescopes. The Large Adaptive Reflector (LAR) is a novel concept being developed in Canada to meet this challenge. A prototype with a 200-350m diameter reflector, operating up to 2 GHz with a bandwidth of 750 MHz is planned. With a collecting area up to ~10% of the planned SKA, and an array feed capable of imaging a 0.3 deg^2 field-of-view, the prototype would address a number of the most compelling questions in modern astrophysics.
