There are a lot of benefits that can be
realized due to Canada's participation with the ISS Project.
In short terms, since we developed the Canadarm and are
letting them use it, astronauts and cosmonauts do not have
to work outside the ISS, in hostile space environment as
much. And they will be able to finish building the ISS
faster because of the Canadarm. The Canadarm will also be
used to maintain and service the ISS, and service payloads.
In the long term, Canada can provide support, new
inventions, and tons of ideas for the ISS.
