Need some help here, I am a US citizin , My wife is a permanent resident (green Card) here in the US. She has her passport from the Philippines ( passport from Philippines). Will we need to get her a visa to go to Canada for about four days???

Countries and territories whose citizens require visas in order to enter Canada as visitors

Citizens of the following countries and territories require a Visa to VISIT or TRANSIT Canada:

P
Pakistan
Palau
Palestinian Authority
Panama
Paraguay
Peru
Philippines

I understand this as yes, a visa is needed. The green card gives you the right to come back to the US. Entering Canada, they want to know where you have a citizenship, not a temporary permission to live.
