Razak Ioyal and Seidu Mohammed know the scars the trek to Canada can leave -- both temporary and long-term.

"The doctors had to cut all my fingers," Mohammed says. They took skin from his thigh to help repair the skin burned by frostbite.

The two men from Ghana had no idea the journey would be so emotionally and physically brutal when they set out in December for Canada.

"When you step your leg in the snow you can't pull it out. So you have to put your hand to help your feet to pull it out," Ioyal says.
