The Canadian customers of MFG got their money back within 10 days of the MFG bankruptcy. The accounts that have lost money are either USA or UK based. In Canada, re-hypothecation is not permitted. I got these comments from a Canadian MFG account holder:
The trustee where segregated MF Global Canada customers' funds were held was RBC Dominion Securities. I don't think any of these funds ever left the trustee in Canada. Likelihood is if they left, the Canadian government would have made the parent Royal Bank of Canada eat up the losses and make full restitution.
