How Do We Get Better Cell Coverage in My Area?

I live in a country residential area in the Comox Valley on Vancouver Island and we have horrendous cellular service. Like, zero bars of service. In my area, we need to either use “calling over wifi” to make a cell phone call, or drive 15 minutes into town and sit in the parking lot of the grocery store to make or receive a call. Wifi calling does not always work and when it doesn’t, I cannot make or receive phone calls. This is not only a convenience problem, this is an economic problem - because I work out of my home. But most important of all, this is a safety issue: if an emergency occurs and I need to call 911, chances are my cell phone will not work and I will not be able to contact emergency services. How do we go about getting more cell towers in my area to improve cell coverage? Not having reliable, effective and consistent cellular telephone service is a serious issue.
