I'm going to leave this to one of the guys that are familiar with Canadian codes. There are some code issues involved if dealing with a US installation and I do not know how Canada deals with them so, I'll leave it to the guys that know.

Some floro fixtures have a power factor correction capacitor installed
in them, this cap can cause some ground current to flow.
This is most likely what is tripping your GFI's.
You can remove the cap and see if this solves the problem.
As I am in Australia, I dont know for sure if your codes permit this.
But in Australia these caps are not manditory,
They are a technical nicety not necessity.
