Capt Apache,
Almost right, but it's two years out of every five in Canada (730 days technically). So you get three years to move there once you have "landed" yourself. There is also a get-out clause which states that days outside of Canada but with a Canadian citizen also count towards this total, so if you are married to one, then no worries about counting the days. Its all on the immigration website, although the fine print requires digging.
