“My oboe is my life, it’s my profession, it's my love, it’s my voice,” said Ron Cohen Mann.
Cohen Mann is in Montreal for the summer to play with Orchestre de la Francophonie, a local ensemble.
After playing the show on Sunday, Cohen Mann went to a cafe with a friend.
He says he left the $10,000 woodwind instrument tucked away in his backpack right under his chair.
However, when he looked for his bag, he noticed it was gone.
"My guess is someone just swiped the backpack, probably intending to pick up a laptop, and not knowing what was inside," said Cohen Mann.
For the last three days Cohen Mann has been looking all over the city for his oboe.
"After it was stolen we went through a bunch of garbage and alleyways in case someone had dumped it," said Cohen Mann.
Cohen Mann says the instrument is insured, but it will be hard to replace because it was picked out for him by New York Philharmonic Orchestra's chief oboe player.
"I tried it and my eyes lit up. I knew I had to buy this instrument, and this was the one for me," said Cohen Mann.
Cohen Mann has filed a report with the Montreal police.
He's offering a $1,000 cash reward to anyone who can help him find his oboe.
