On Friday, the REM took its first official trip, marking a new era for public transit in the city. The transit agency reported that more than 120,000 people rode the new automated LRTline this weekend, when trips were complimentary to celebrate its launch.

Elsewhere in the city, protesters gathered atPhillips Square in downtown Montreal to call out human rights abuses in Iran.

Harsh clouds and intermittent rains castshadows over the final day of the Just for Laughs comedy festival on Saturday, but performers and the public ultimately had the last laugh.

At one point in the evening, one of the comics made a dig at the giant set of teethoverlooking the stage.

"There's nothing more terrifying than turning around and seeing that," said comedian Mike Falzone, during the LowKeycomedy show hosted by Paul Elia andDave Merheje. "It's like, how fast can I tell jokes and get outta here before my sleep paralysis demon eats me alive?"

At the Old Port, Montrealers were determined to enjoy their time even as the downpour began Sunday evening.

The weekend ended with a bang several hundred of them as Era of Rock,the United States' entry into this year's International des Feux, launched from La Ronde, lit up the Montreal night sky.
