It looks like Jose Aldo will not be fighting on the UFC 149 fight card in Calgary, but instead lead UFC 147 with a title defense against Erik Koch in Brazil, according to MMAWeekly.
Nothing has been signed at this time, but once the UFC nails down a venue for UFC 147 it will need a top Brazilian act and Jose Aldo is just that.

Sweet! Aldo is fighting again. He is my favorite fighter in UFC. YES!
