THE CANADIAN LUMBERMEN'S ASSOCIATION TOWER
Anyone who has ever walked past a building construction site knows that these projects generate so much interest from the public that the builders put portholes in the wood-panel fence surrounding the site in order that passersby might take a peek at the building's progress. In the summer of 1965, the Canadian Lumbermen's Association built a tower on the Expo 67 site to serve this very purpose. Made of wood, naturally enough, the tower was meant for "sidewalk superintendents" who wanted to watch the construction of the biggest building project in Canadian history. Most of the pavilions at Expo were meant to be temporary, but none more so than the CLA tower: it was dismantled before Expo opened, its purpose having been served.
