Raw video:June 10/08:Window washers caught by thunder-storms' high winds @ Place Montreal Trust tower. [2008-06-10]
Not shown: they made it to safety when someone broke a window from the inside and helped them in.

"Gusting winds left a pair of window washers stranded 35 storeys in the air at Place Montreal Trust. Their work platform started swinging so hard from side to side that "at one point, it was perpendicular to the building and was blowing in the wind," said Jeff Smith, an office worker in the downtown building.

Smith and his co-workers watched on the edge of their seats with a "front row view" as the cleaners clung to the platform for nearly a half hour, Smith told CBC Radio.

They eventually gained access to the building on another floor through a broken window, he said."
