Allied soldiers in Siberia 1918

[Howard Weinert]

Some time ago I posted a postcard showing Allied soldiers from 6 nations in Siberia in 1918 wearing summer uniforms.
I recently found a similar card showing the same men in winter uniforms, except a seventh soldier was added in position third from left.
Can anyone tell me if he is Canadian? The others, left to right, are American, British, Chinese, Italian, Czech, Japanese.
