CN Tower dethroned by Dubai building

The CN Tower is no longer the world's tallest building or free-standing structure.

For years, Torontonians have known that the tower's claim to fame was at risk, as planned towers around the world threatened to break its 30-year-old record.

Finally on Wednesday, a structure under construction in the Arabian Desert succeeded in passing the Toronto tower's 553.33-metre height.

Burj Dubai — a glitzy hotel, residential and commercial building being built in Dubai, United Arab Emirates, for a price tag of $4.1 billion US — will be more than 150 stories tall when it reaches its final height of 800 metres.
