NORTH VANCOUVER, B.C. - A 55-year-old man has died while climbing the Grouse Grind in North Vancouver and the hiking trail has closed while the coroners service investigates.

RCMP Cpl. Richard De Jong says the unidentified man had completed about three-quarters of the 2.9-kilometre hike on Grouse Mountain when he suffered a heart attack.

He says the death happened at about 10:30 a.m.

Neither De Jong nor coroner Robert Fisher knew if the man was accompanied or climbing on his own.

The challenging hike, dubbed Mother Nature's stairmaster, opened for the season in early May.
