Move the dialog box out of the way to see a preview of the crop area size. This will give you an idea of what section of the data will be cropped. The crop should only target fsatoronto_area layer and the streets will remain untouched.

8.Click OK to complete the crop.

The fsatoronto_area layer is cropped to the crop extent and the streets were untouched because they were not included as a target.
