I'm actually in the Toronto, Canada area, having moved up here in 2007. My wife being Canadian and all that.
No problem to your question. The thing on my head is a cochlear implant. I have one on both sides. Hearing aids were becoming less and less helpful and so by summer of 2012, the hearing in my left ear was essentially shot. Had the cochlear implant surgery on the left side in 2013 and the right side in 2015. It's been great! If you have more questions, fire away. I like sharing my experiences about this.
