The Navionics Canada+ card is fairly good. You should get lake outlines and decent coverage of the major lakes, but like was posted above, the quality of the actual depth contours will not be all that good.
If you use a Lowrance sonar unit, check out this site and see if any of the lakes you fish are on the list and have some coverage. The map quality of the Social Maps will be FAR better than anything on the Navionics cards, and they are FREE to download, just sign up for an account.

If your Lowrance unit is an HDS Gen3 or newer, Elite TI, or Hook2, you can also create your own maps just by plugging any blank microSD card into your machine.
