Here is a semi-complete list of everything I’ve come in contact with that aren’t available in Canada:

• Lala (international copyright issues) -> See Video <-
• Pandora (international copyright issues) -> See Picture <-
• Hulu (international copyright issues; this includes embeds for any associated companies including the Comedy Channel for example) -> See Picture <-
• Google Voice (won’t forward to Canadian numbers; suspicion is that it’s CRTC regulations on E911 services) -> See Picture <-
• Amazon MP3 -> See Picture <-
• Amazon Prime
• Amazon streaming TV and movies
• Netflix Streaming (Netflix physical media rentals are provided by Zip.ca)
• textPlus (won’t accept Canadian phone numbers; although, GOGII is conducting a beta regarding that, see here.) <b>[UPDATE! textPlus is now available in Canada as of February 16, 2010]</b>
• Motorola Droid (or GSM/UMTS version called the “Milestone”) – no carriers yet
• Nexus One (won’t ship to Canada; Nexus One uses irregular UMTS bands that none of the major 3 Canadian carriers use; AWS is going to be provided by WIND mobile — currently in Toronto only)
