Reading over the provincial and federal policy on towers. All say that the company should work with the municipality on location.
They all also mention that towers should be part of the official plan. So looking at the plan, I don’t see anything on the plan.
Check it out here.

So it is interesting that nothing is in the plan. But look at the URL, did this plan started in 2012 when 4G wasn’t even out yet.
