are engineering degrees from australia recognised in canada?

Answer 1

Engineering registration in Canada is done separately in each of the provinces. You would wish to contact the appropriate accreditation body in the province in which you wish to practice. In British Columbia for instance see http://www.apeg.bc.ca/ or for Ontario see http://www.peo.on.ca/

For a general discussion of foreign accreditation in Canada including a section on engineering see this:

Good luck

Answer 2

Yes, they are recognized by canadian universities
