It happened around 12:30 p.m. at the Canmore Golf and Curling Club.
Naomi Nania with EMS says the man in his early 60s was breathing and had a pulse.
He was taken by ground ambulance to Canmore hospital, then an air ambulance took him to Calgary.
There are currently no severe thunderstorm warnings issued for the Canmore area.
Meteorologist David Spence says more than 90 per cent of people struck by lightning survive.
“But, almost all of them are injured in some way. They are all burned to some extent, the lightning can get into their brains and mess with their minds, erase some memories. You brain controls your movement as well, so if lightning gets into your brain it could paralyze you or impair your movement.”
Spence said think of thunder as an alarm bell — once it goes off, get inside.
