As the members are likely aware, Canada now has a representative to the African Union, in recognition of the significant and important role that the African Union plays on the continent, including in peace and security. The challenge in Sudan, though, is that there are so many actors who are seeking ways forward with these particular belligerents and others in terms of a ceasefire.
Canada does support the African Union efforts at supporting dialogue, particularly ones that they've hosted where they are broad and inclusive with regard to civilian actors; but, like the other parties there, they are also having trouble finding a way forward.
