About Tamim's availability, I've been in constant touch with one of the media liaisons of the event, and I was informed that the organizers are still in talks with Tamim's agent. As it stands, he is still a contract for this match, and nothing has changed on that front since the IPL signing. But realistically, I don't expect him to get a release from Pune for a week. If I'm not mistaken, an IPL contract does not allow any player to leave camp unless it is due to national duties.
About the broadcast, the match will be telecasted by Rogers Sportsnet (and likely streamed on their website -
www.sportsnet.ca), which is a prime sports channel of Canada, owned by the media giant Rogers. Cricket has slowly started to come to mainstream media here in Canada, starting with the 2011 World Cup, when Rogers struck deal with Cricket Canada and ICC to bag Canadian broadcasting rights for major ICC events and the IPL.
