I have Dish Network so I probably won't be much help to you. I am able to watch the ESPN broadcasted games. If the game is strictly on ACC Network through Watch ESPN I am out of luck as they do not allow viewing in Canada. One of the local ABC channels carries a few of the ACC Network games so I am fortunate in that regard. They picked up 6 games this year. Other than ESPN, CBS and this local station there were 12 games this season for which I had no TV. I am blacked out on any SU games shown on Regional Sports Channels. For those I had to find a different streaming site to watch. However, for some reason, this season they are not being shown even though the games are highlighted on the streaming site guide. Very frustrating.
My son used to live in Ottawa and had Rogers Cable with the various sports packages. He would end up getting just a few of the SU games. You would think a Syracuse/Duke game would be one the Canadian Cable company would pickup, but as mentioned in prior posts, Saturday nights are tough to find anything other than hockey.
Now if you bring your own computer which has an American VPN with access to Watch ESPN then you might be able to watch it through hotel or a relative's Wi-Fi. Can't say if Watch ESPN would be picking up the Country source of the W-Fi?????? I use a HDMI cable to the TV to watch my streams so you could do that as mentioned previously. Although most of the streams I had this year were not very good. If all else fails you can go on-line to WAER radio and listen to the game.
Good luck, hope you can find it. The Duke game will be my last TV game of the conference schedule.
