City crews have capped a large water main break outside Old Cummer GO station but the area remains coated in ice and closed to vehicle traffic.

The water main on Leslie Street north of Finch Avenue East ruptured in frigid temperatures early Tuesday and sent water blasting 10 metres into the air. With morning temperatures in the -20 C range, the water quickly turned to ice, making the road treacherous for both cars and pedestrians.

CBC News overnight reporter Tony Smyth described a "mountain of ice" forming on Leslie Street.

Crews capped the break just after 6 a.m.

The city has brought in heavy equipment to clear the ice and snow.

"City crews trying to access the site are slipping and sliding on the ice," reported CBC's Jasmin Seputis at 7:30 a.m. "Obviously with the road in this condition, it's been blocked off. There's no word yet on when Leslie Street will reopen."

There is no access to the station parking lot, but the station is open to pedestrians and GO service is not affected.

The TTC's 51 Leslie bus is diverting both ways via Finch, Don Mills Road and McNicoll Avenue.
