You would probably have the best chances getting admitted to uWindsor. But I wouldn't count on it.
Your GPA is slightly higher than their average, and your LSAT is about 4 points below their average (which makes a huge difference when one is speaking of percentile scores in the 150 range).
As for UNB and USask, I believe both your LSAT and GPA would be considered uncompetitive. Each has an average LSAT around 160, and GPA between 3.5 and 3.75. But if you can come up with a really compelling reason to attend law school, you might convince them to at least consider your application.
Best of Luck.
