GOL-TV Canada is owned by MLSE (Maple Leaf Sports Entertainment) - 51%; with the other 49% held by the original GOL-TV Group.
GOL-TV USA have just announced that they will start broadcasting in HD on August 1st, 2010. One would suspect that GOL-TV Canada would follow suit as they are already approved by the CRTC to broadcast in HD and have moved to HD facilities in Toronto at the end of last summer.
They currently show MLS matches in HD but on dedicted channels (such as Special Event channels). Unfortunately, this is only true for Shaw and Cogeco systems. For some reason, no HD broadcasts are scheduled for Bell. Last summer they used channel 399 to show a friendly between Toronto FC and Real Madrid. With about 90% of their programming coming from GOL-TV USA, I wouldn't expect a HD channel in Canada until August.
