2010? There must be a mistake. The expiration date of immigration visa should be the exactly one year after medical exam. I'll suggest you land before that date regardless this 2010 issue to avoid any potential trouble.
Immigration visa is only for one entry which means it will void after your landing. After landing, you will need Maple Leaf Card, which will be ordered at the time of landing if you provide a Canadian mailing address, to travel internationally.
3 years means accumulated date of staying in Canadian in any 4 years (not 5 years, 2 years of any 5 years for keeping PR status) period. If you move to Canada immediately after landing, it will start to count from the date of your landing.
