Stamp with no handwritten date - Supervisa

[rohansekhri]

I have come across many posts and I'm still confused if a stamp without a handwritten date means 6 months of stay or 2 years of stay.

CIC seems to be sending emails with 6 months and 2 years as valid stay to different people and this link says it's two years and CIC call centre agents are saying 6 months as well.

It will be great if someone can clarify this.

Thanks
