Answering my own post...lol, just found something that I thought might help others who are looking for this type of stuff as well. You can customize a map on the ministry of natural resources website, adding lake features by clicking on the layers folder. Click the layers folders to add layers such as lake bathymetry, and in the upper right corner of the map there is an option to make it larger. I have yet to figure it out completely, but seems pretty straight forward and looks like it might be useful. So far it doesnt appear as though you can add the actual depths to the lake contours, but at least it shows them.

STEPS
1. accept the disclaimer.
2. familiarize yourself with the options at the top of the map (hover your mouse of the icons).
3. switch map to XL size (top right of map is where this option is)
4. zoom in to your area of interest
5. on the left side of the screen is some tabs, click on the layers tab to make it current
6. click the natural features folder, then water and navigational aids, then water features, then great lakes bathymetry (shows depths), and make sure lake ontario bathymetry option checked. You can also turn other things on here that are helpful, such as the markers and bouys.
7. refresh your map, and you should see the depth contours
8. To see the depth of each contour pick the icon on top with an "I", then click on the contour line and the information will appear on the left side of the screen (in meters...to get feet, simply multiply the number by 3.27)
9. If you want to measure the distance between two points (in case you want to pace your distance from shore) there is an icon at top, looks like two arrows with a tape measure. Pick first point, then pick second point, and it gives you the exact distance. From surveying I know that I can pace 100m within 2m accuracy by stretching my step just a bit. Takes a bit of practice, but helps for stuff like this. If you have a GPS unit, this gives coords as well and you can plug them into it.
