In Canada our internet became much faster for cheaper with better customer support when the government allowed competition from smaller players. Telecom also got better when they allowed a foreign competitor to compete against the government mandated oligopoly. But the market is still heavily regulated in a way that benefits the existing monopolies.
What the CRTC did was force the big players who own all the infrastructure to allow resellers to resell their services, and have to pay no more than cost to the big guy.
Those "smaller players" have a marginal involvement in the entire network aspect. They usually host ISP emails and sometimes DNS. Some of them do provide better customer service than the upstream big guy. At least until they need upstream help to resolve your issue, then it takes forever.
The other type of small players, who install their own infrastructure in smaller municipalities, were not impacted by this change. Some provinces (SK, QC) do give generous grants to those small players to install fibers. But AFAIK there is no federal involvement specifically to help them.
