Default Determining unbalanced loads and sizing neutral

Under 200A neutral conductor must be equivalent to phase conductor

But above 200A, it can be sized based on the unbalance loads... how does one estimate these loads. Any rule of thumb?

There should be a section in the CEC that covers the calculations and wire sizing.

CEC rule 4-024(2)(a) and (b)

That's code, not a rule of thumb!
