This is one of those films I think I might end up spending the rest of my life trying to get a copy of. I saw it when I was about 18 by sheer luck of turning on the TV at the right time - late night when Channel 4 was still good (UK moan there, sorry everyone else). It is a superb film, one of those that lodges in your mind forever after one viewing. I don't want to risk a spoiler here, but it's a road movie OK? The journey is the story and all that. The central character is sympathetic and pushing her limits as a person but not lost and hopeless, the characters you meet along the way are all interesting and strange, pursuing their own fates. The photography (B+W in 1989), characters and plot give the whole thing an other worldly feel that is very engaging and for general not-corny quirkiness this film must rate highly. Also, the landscape of Canada (man-made and natural) plays a big part in what I remember of the film.
