I am flying: EDI>AMS>PEK>CAN>SYD on the first leg

and SYD>CAN>SHA>AMS>EDI on the second leg. I only plan to leave the airport and go into China in PEK and SHA. I originally applied for a Multi entry visa, however they will only grant me a double entry permit.

Will the double entry permit suffice if I am stopping in CAN only to change planes and continue on?
