Thanks Mike. Vimeo's having problems loading over my internet connection....and the little bits I did see seemed to have a lot a fat bald Canadian hanging around in the background...bit off-putting.....
Bell Media have now contacted me and we are trying to resolve their admitted unauthorized use.
The matter has become slightly more complicated as their explanation for using the video was that they had seen it on my website, and they had asked permission for other videos of mine in the past (not this one) and I had always refused as they do not pay for any licensing fee (you get a credit, whoppee). They then say they saw it on YouTube on what they though was my channel as the user was called LiquidG. When I searched for LiquidG and my video I found nothing. LiquidG does exisit, but has no underwater videos. When searching all of YouTube I could not find my video. They said they sent the user an email requesting permission, and he agreed they could. They have admitted this was an error.
When I asked them for the link, they sent me a YouTube url to a video that now said it had been deleted by the user. This user was called LiquidG01. His channel has 5 videos on it, all uploaded about an hour after my initial call with them. There was a Google+ link, which when clicked showed me that my video had been upload at the same time as the others, then deleted. I have screen grabs of this. So the video did not exist ever on YouTube, and definitely not when they said they saw it on the 3rd April. It really seems they are trying to deceive me about their 'innocence' in using the video.
I will wait to see what they have to say tomorrow.
