The International Space Station was first conceived in the early 80's as Space Station Freedom. It was originally intended to be a counter to the Russian Salyut and Mir space stations. At the same time, the Russians were developing Mir-2 as a replacement for the space station Mir. Because of budget and design contraints, Space Station Freedom never made it past minor tests. Shortly after the collapse of the Soviet Union, Mir-2 was also on the verge of being cancelled. Through international cooperation, both space station projects were revived. In 1993, the Clinton administration announced that Space Station Freedom, Mir-2, as well as Europe's Columbus Orbital Facility and Japan's Kibo would all be combined into one large space station: The International Space Station. In 1998, construction of the International Space Station finally began with the launch of Russia's Zarya module, originally designed for Mir-2. And now over 10 years later, ISS is almost complete.

the iss is the biggest space station and only space station

Canada is not in space, so therefore there is no space station in Canada. Canada does have an arm on the International Space Station in space.
