Yes but I only attended the Guidance and Counselling Seminar to acquire the Guidance & Counselling Certificate required for renewal of my passport using my husband's surname who is a Canadian citizen. If may visa ka na, mas ok yun dahil they will issue the GCC certificate and the CFO stikcer after u attend the PDOS.
Yung seminar sa Makati yun yung sa COA (Canadian Orientation Abroad) initiated by the Canadian Embassy, pre-departure orientation din yun pero di naman ata required. Kung gusto mo lang mg attend hehe. Canadian Embassy will give you the flyer ata kpag na issue na sa'yo ang visa. Here's their website for more infos ( http://www.iom.int/cms/en/sites/iom/home/what-we-do/resettlement-assistance/canadian-orientation-abroad-helping-fut.html)
Hope it helps.
