can I Enter Canada with a visa on my old passport?
Yes, as long as the visa remains valid. (Canadian visas are not normally valid beyond the passport's expiration date.) See Can I travel to Canada with valid visa on old/expired passport?
I will take both passports with me?
Yes. If you don't bring both passports, you won't have the visa.
and do I really need a six months valid passport when entering canada?
No. Canada requires only that the passport be valid for the duration of your stay. If you show up with a passport that is valid for a period shorter than six months, you will be admitted until the day on which your passport expires. See Passport validity for Canada.
