The Canada Science and Technology Museum may be primarily a construction site these days, but museum officials are ensuring it's at least a colourful one.

Dozens of aspiring artists gathered Saturday at the St. Laurent Boulevard site to design a nearly 170-metre-long mural on the construction wall.

The project is the end result of a contest the museum launched in April. They asked Canadian students between the ages of four and 19 to submit their designs for the wall.

On Saturday, professional graffiti artists were on-hand to make the mural a reality thanks to a partnership with the House of Paint festival.

"You don't just do science without being creative," said Alex Benay, president and CEO of the Canada Science and Technology Museums Corporation.

"We wanted to see, from an artistic perspective, how youth across Canada were engaged with science and tech. And they came up with some pretty cool drawings."

The museum was forced to close its doors in September 2014 after maintenance workers discovered mould in its walls, following years of complaints about leaks in the roof.

It's expected to reopen in the fall of 2017.
