What will be important in your situation is that while you have international banking experience your HR experience will need to be updated to the Canadian marketplace.
I may suggest you don't necessary focus on the industry but rather your core and transferrable skills which could likely apply to many industries.
If you want to stay in the HR field, depending on the province you immigrate to it will be critical that you have indepth knowledge of the Canadian employement laws, Health and Safety, privacy laws, human rights, etc, etc.
I would suggest you investigate taking a virtual courses to get your Canadian CHRP (HR) Designation.
