Difficult question because the basis between the ponds is not the same.
The short version is USA/Canada classes by gluten level and Europe more
by fineness of grind.

Is there any clue on the bag as to gluten level of the one you have?

For the most part, you probably have what will work out as 'AP' flour
here and yes, it works for bread. Adding a little extra gluten powder
is a good thing if you need a lifting bread.
