Whether you want to believe it or not, the US Dept. of Defense does control 
the satellite GPS transmissions, and has admitted to intentional random error 
offsets.  Private sources have confirmed these by watching fixed points 
periodically "move", while other private sources are selling correction info. 
 
The errors aren't "built in" to the hardware, but are in the way it's been 
operated.  As a Canadian, you perhaps are a secondary beneficiary, with less 
direct say in the arguments where our military is being pressured to end the 
practice of inducing errors.
