Hey 'Biola, not true. You will have to stay till you get your PR Card which takes about 4 weeks, last time I checked. That's what will allow you "move around". By move around, i assume you mean the ability to travel in and out of Canada.
On the other hand, if you have someone in Canada whose address you can use, you can have the PR Card sent there when it's ready, thus allowing you to leave sooner... The person will have to mail you your card so you can re-enter Canada....
.... but all this is information that you won't need for a while if you sent in your application within the past 2 yrs to the accra office (according to other people's time lines).
Good luck though!.... and like you said, just take your mind off of it and do fun things while you wait...
