Query: Canada and the SKA from 2020-2030   This white paper submitted for the 2020 Canadian Long-Range Planning process
(LRP2020) presents the prospects for Canada and the Square Kilometre Array
(SKA) from 2020-2030, focussing on the first phase of the project (SKA1)
scheduled to begin construction early in the next decade. SKA1 will make
transformational advances in our understanding of the Universe across a wide
range of fields, and Canadians are poised to play leadership roles in several.
Canadian key SKA technologies will ensure a good return on capital investment
in addition to strong scientific returns, positioning Canadian astronomy for
future opportunities well beyond 2030. We therefore advocate for Canada's
continued scientific and technological engagement in the SKA from 2020-2030
through participation in the construction and operations phases of SKA1.
