Network Coverage in Guelph

I live near Guelph university on Gordon St. by Kortright Rd.  Cellular service is abysmal, even outdoors, never mind inside a condo.  Calls barely come through on the street.  Phone is in "H" coverage, but I would gladly settle for 4G. 

Looking at the tower locations, there is a huge dead-spot.  Are there any means of auditing coverage in the area?  Is there someone to contact at Telus to see if there is anything in "the offing" to improve the situation?

I cannot see paying for a service that does not work at my home.  I would prefer not to switch to Rogers, (who have more towers in the area) but that may have to be the case.
