The U.S. Supreme Court upheld President Barack Obama's health care plan on Thursday, in a 5-4 decision.

The President's health care plan, considered to be a key part of his domestic agenda, has been opposed by Republicans and many right-wing Americans.

Many Americans who were upset at the Supreme Court decision took to Twitter to voice their anger. Weirdly enough, many Americans tweeted about 'moving to Canada' to escape socialized medicine.

"I'm moving to Canada, the United States is entirely too socialist," tweets @wallyweldon.

"The supreme court upheld Obama Care. That's it. I'm moving to Canada!," tweets @lucasdargis.

Of course, Canada is no stranger to socialized medicine, with some provinces having universal coverage as early as the 1950s.

In fact, Canada's universal health care is one of the things that Canadians can agree on.

Of course, some Americans know a bit more about their neighbour to the north.

"Hey, Republicans saying they are moving to Canada.... Have fun with totally govt run healthcare up there! #NorthOfTheBorder," tweets Ethan West.

Wait till we tell them about our taxes. Let's not forget the whole legalized gay marriage thing.
