Yes. The colors are designated as International Orange and (believe it!)
International White. Transport Canada and Industry Canada specifications are
very similar to the U.S. I do think that enforcement of the prescribed 1/7
paint pattern is a bit less stringent in Canada, though. Many towers just
have alternating red and white sections with red at top and bottom.
Strobes are required on everything over 300'. Below that, flashing red lighting.
