Big stack attack in the Portlands

A third stack arose at the Portlands Energy Centre, bigger than the first two, and a base for the fourth has already been constructed. While the above ground structure is impressive, the amount of underground construction shown in photos on the Ontario Power Authority website is equally impressive.

Putting on my Made In Canada hat though, I wonder why the stacks had to be brought in from Thailand. Is our manufacturing technology that inefficient, or that incapable that we could not produce this in-house? Sad
