Canadian rose growers: question re blackspot

I did not spray last summer, my first in zone 5b PEI. I had some blackspot and think I'll have do do something to deal with it this summer. What fungicides, if any, do you use to control it and where do you buy them? Bayer Advanced Disease Control does not seem to be available in Canada and I wonder what the options are, apart from garden sulphur. Thanks.
