MONTREAL - Firefighters have evacuated a building in downtown Montreal because they fear construction taking place next door could cause a collapse.

Renovations have been taking place on a building at the corner of St. Andre St. and Sherbrooke St. for several weeks, and engineers who inspected the building last week noticed it had started to shift.

As a result people were ordered to leave that building last Friday and not return until the structure was fixed.

Now, on Wednesday morning, firefighters worried about the continual shift have ordered the lower floors of the building next door to be evacuated.

They are concerned that if parts of the adjacent building come loose, or if a wall falls, the building at 1001 Sherbrooke St. E. could be damaged.

That means several classes at UQAM, as well as College April-Fortier, and the LaSalle Conservatory have been cancelled until new space can be found.

Engineers are going back to the building undergoing construction, and if they determine it cannot be repaired will recommend it be destroyed.
