Money that you earned before you became a PR is considered property, not income, so there are no taxes. You can just transfer to your Canadian bank account. The banks will not withhold anything for tax (which I suppose was your question).
If you have assets held outside Canada (including cash) worth more than $100,000 CAD when you file your taxes, you should report it on the foreign income verification form.
Once you are resident in Canada, your international income is taxable (subject to tax treaties that may lower the burden).
