问一下，挖围栏深度

[射手座牛宝宝]

请问在Barrhaven 挖 fence, 柱子要挖几米深？我联系的公司说3 feet 够了，但是这还不到frost line呢。

May I ask, why should it reach the frost line?

This is what I know: The idea of digging below the frost line is that this practice does not permit the water, that might collect under the post, to freeze and push the post out.

I see.

Now my further question is, how deep is the frost line from the ground? In other words, how deep should the post go?

Frost line is around 4 feet as far as I know.

Yes, you are correct. I've searched online and the frost line in Eastern Ontario is said to be about 4'.
