Lol, this is my dream as well... I was wondering when they would ever have a show in Canada...
I don't want to sound like a pessimist or anything, but personally,the chances of them coming to Canada are very slim... mainly because I have a REALLY good feeling that they will get mixed up with our fellow neighbours down to the south (United States =P)
However, if I remember correctly, Haruna likes to watch Hetalia Axis Powers (this was when they were in an anime convention in Anaheim I believe), which DOES have countries that many including Canada! Also, through Haruna's blog (don't take my word for granted, this is all from what I remember from her blogs), she likes the cold weather, so it's only natural for her to come to Canada xD.
So Canada should still be out there at least for them. But then again, as our friend, HaruRinaMamiTimo had mentioned the costs and their filled up schedules for 2014 seems very unlikely that they'll come to Canada this year.
There is hope. I know in Toronto, every May (or around that time) they have AN (Anime North) and maybe... just MAYBE they could be a special / honourary guest... just like they were in the AN in 2011. If they actually do come to Canada (

) my best guess is that they'll have a concert in Vancouver... (It's the closest to Japan and I'm pretty sure there is a heavy Japanese influence there mainly due to history)
Believe me, you are not the only one who wants SCANDAL in their own respective countries. So the only thing we can do right now is to pray (I know I am LOL). But I believe someday, they'll go beyond the borders of Asia and play more in other continents like Europe and North America.
