You can visit one or two largest bank in your country, they usually have corespondent bank in Canada. or come to a bank that located near Canada embassy, it usually handle visa application fee for canada.
I know BPI has an agreement with Scotiabank that your DD will clear after only 10 days. Pag umattend ka sa COA, may representative sila dun to discuss about it. Pero sa Paseo branch or Head Office lang ata available yun.
