Hi Michael,
AME conversion from Canada to Aus is a complicated but not impossible task - there will be significant cost involved!
The Australian system is still a little in flux as we have a new EASA based system running for Heavy aircraft maintenance (B1 - Mechanical /B2 Avionics licenses). Our B1/b2 system is competency based (specific competencies need to be demonstrated) and assessed by a college who then advise CASA to issue a license.
The old exams + experience system is in place for light aircraft licensing until 2019 after which it will move to a competency based system.
Since you will likely undertake your application under the competency system the process can be done under a "recognition of prior learning" process. To undertake this process your would provide evidence (not just your license - collect everything you can from your career, it all helps) to the Registered Training Organization (RTO) who would assess it to make sure it meets all the Australian requirements. The RTO would then advise of any gaps (and the cost to make them up) and set up a plan for you to do the gaps. Once you had completed everything they would advise CASA who would issue you a license.
A list of RTO's approved to assess basic licenses can be found here:

Not that only some of the above are approved to assess Canadian licenses. Standards and cost for the RPL vary considerably so shop around.
Any other advice required drop me a PM
