As a general rule - and it is the same for Canada - refugee travel document is valid for travel to all countries except the one you claimed the persecution from. I.e. if you fled USA and granted refugee status in Canada, you cannot use this document to travel to USA.
Regarding the question "whether I can entry country X only with a refugee travel document or I also need a visa", you shall use Timatic. Make sure you enter your document as "refugee travel document" and not "passport".
