Here's why:
* Different broadcast networks: The US version of "Dancing with the Stars" is aired on ABC, which is not available in Canada.
* Voting restrictions: Voting is generally restricted to residents of the country where the show is aired. This is often due to regulations regarding phone/text voting and the specific broadcast rights agreements in place.
* Canadian version: Canada actually has its own version of "Dancing with the Stars", which is aired on CTV and Canadians can vote on that version.
Therefore, while you might be able to watch the US version online, you wouldn't be able to participate in voting for the American contestants.
