Canadian visiting limits

[bestest 1]

I have been searching the forums and am pretty confused. There is a lot of contradictory information from different people in regards to a Canadians right to visit without a visa.

I understand that a Canadian doesn't need a visa nor is it under the VWP when he enters. He enters as if he has a B-2.

What is the allowance? 180 days or 90 days? is this per 365 day period or per calendar year or unlimited? I understand that the CBP officers won't let a visitor in TOO frequently because they will suspect that he lives in the country. But, is there specific rules to this or is it based on his discretion? I've seen people say that a Canadian must be in Canada at least as much as in the US. Is that just so he shouldn't appear to be living in the US?

If a Canadian spends more than 180 days out of the country, their provincial health care can become void because the citizen is no longer deemed a resident of that province.

180 days is the limit per visit. Visits are up to the CBP. However, who can travel THAT much to the US without a stable job or home?

good luck
