The Canadian Arrow was a privately funded, early-2000s rocket and space tourism project concept founded by London, Ontario, Canada entrepreneurs Geoff Sheerin, Dan McKibbon and Chris Corke. The project's objective was to take the first civilians into space, on a vertical sub-orbital spaceflight reaching an altitude of 112 km.

A sub-orbital spaceflight is a spaceflight in which the spacecraft reaches outer space, but its trajectory intersects the surface of the gravitating body from which it was launched. Hence, it will not complete one orbital revolution, will not become an artificial satellite nor will it reach escape velocity.
Science and Mechanics cover of November 1931, showing a proposed sub-orbital spaceship that would reach an altitude 700 miles (1,100 km) on its one hour trip from Berlin to New York.
The X-15 (1958–1968) was launched to an altitude of 13.7 km by a B-52 mothership, lifted itself to approximately 100 km, and then glided to the ground.
