Canada has now become a full partner in the Thirty Metre Telescope (TMT). The TMT is one of the class of extremely large telescopes coming online in the near future, along with the European Extremely Large Telescope, and the Giant Magellan Telescope. These engines of discovery are designed to be highly productive scientific instruments to move our investigation of the universe to the next level. On 2015 April 6, the Prime Minister announced that Canada would become a full partner in the Thirty Metre Telescope project, committing $243.5-million, amounting to a 15 to 20 per cent share in the costs. This will ensure access of Canadian astronomers to the TMT, a voice in its management, and ongoing involvement in its design and implementation. This is a success for the Canadian astronomical community, and will pay scientific, cultural, and economic dividends now and in the future.
