It’s a new Bell Let's Talk Day record.

"I'm truly overwhelmed by the depth and breadth of the non-stop conversation about mental health this year and by what we've all built together," said Clara Hughes, Canada's six-time Olympic medalist and Bell Let's Talk national spokesperson since the initiative began in 2010.

The campaign ran over the 28.5-hour period between midnight Newfoundland time and midnight Pacific time.

It saw a 3.1per cent increase over the 122,150,772 total interactions on Bell Let's Talk Day 2015.

Bell is donating 5 cents per interaction to mental health programs, at no extra charge to participants.
