Check out this great video of a Yukon river canoe journey in 2008, made by Angelo and Calogero of Milan, Italy. They paddled from Whitehorse to Dawson and produced a great film with music and stories.
I met these 2 Italians at a campspot near Minto on the river, north of Carmacks. We spent an evening and morning together, taking photos, sampling Italian camping foods and swapping stories, while meeting up with a local river guide who has a cabin nearby.
See the video at Yukon 08 video at inkayak.it a great website, full of kayak videos from journeys around the world.
