Carrying Multiple Flags

[wwcfoa43]

In Canada, it is against accepted mechanics to carry more than one flag. Recently, we had a situation where an official threw his flag for a hold and then had a bad late hit out of bounds. The players of the non-offending team for the late hit saw no flag thrown (since the official did not have one) and so ended up being called for Objectional Conduct (your USC).

While the players actions are no excused, the use of a second flag in this instance would have communicated that the late hit was penalized and so the further fouls would not have occurred.

So my question is what is the prevailing opinion on carrying more than one flag south of the border?
