I am likely going over old ground here so please allow me to do so. 
(AFIK) In areas served by Bell, Bell owns the local loop, i.e. the 
copper from the CO to the demarcation point at the household or place of 
business. Premises wiring after the demarcation point is owned by the 
owners of the property. But I digress. To carry the POTS (non VoIP) 
service the local loop must, of course, be connected at the Bell CO to 
the Bell telco switches. (Not all local loops are connected to the 
telco's telephone switches. A local loop not connected to the telco 
switches is a dry loop.)

It is where DSL is concerned that my understanding is a bit fuzzy. 
(AFIK) If a local loop (wet or dry) is to carry DSL it must be connected 
through a DSLAM to a backbone digital trunk and the network at large. 
Bell DSLAMs provide their DSL service, either retail or wholesale. I 
have read here that other companies' DSLAMs can be co-located at the CO 
and the local loops can be connected to these third-party DSLAMs and as 
a result will carry DSL services not provided, either directly or 
through resale, by Bell.

In areas not served by Bell, substitute the name of the local telco 
service provider for 'Bell' in the text above. For example, in the 
Goderich and surrounding area, Hurontel is the (a?) local supplier of 
telephone and related services. Hurontel is but one of the many 
'independents' in Ontario.
