In Japan, China and Dubai, they build, dream, and break records with architecture.

In Toronto, the CN Tower stands at an unchangeable 553 metres, and watches helplessly as other contenders creep higher and higher.

It seemed to have lost its champion status in January when the 800-metre — and still growing — Burj Dubai was formally recognized by the Guinness Book of World Records as the world’s “tallest freestanding structure.”

But Guinness, like a teacher bent on giving awards to everybody, is getting more specific in how it describes the concrete wonder. The latest designation the CN Tower can add to its pamphlets? The world’s tallest freestanding tower.

Guinness “re-presented” the award to the 553-metre icon yesterday.

“We’re simply just updating the records, as it should have been originally,” said Carey Low, a Canadian adjudicator with Guinness.

“I understand that some people might think it’s semantics.”
