I am a US citizen. I have been living with my boyfriend since October 2011. I came back to the states in December and then re-entered in January. I left Canada March 30th and came back to the states. I plan on going back to Canada April 18th. My question is, do I have 6 months from April 18th to stay in Canada, or did that 6 month time frame start back in January? There seems to be multiple answers. Some people say 6 months total out of a year, and others say the 6 month time frame starts over each time you enter Canada. Which is it, and can you confirm this?
