Max deck size without a permit?

I have seen conflicting information regarding a floating (detached) deck max size.

Some places mention the usual 107/108 sqft that is the same for gazebos but I saw this site that a non covered deck may be as large as 200sqft without a permit in Barrie:

searching a lot of documents from Barrie I couldn’t find anywhere expliciting the max size.

I was thinking about building a 120 sqft but I don’t want to go through the hassle of going after a permit.
