What is the effect of Sigma on the Canny edge detection?

Sigma: Standard deviation of the Gaussian filter. Good values to start with are between 0.6 and 2.4. Smaller filters cause less blurring, and allow detection of small, sharp lines. A larger filter increases processing time and causes more blurring.
