Coupling access to members area with existing subscription products

Site URL: https://www.hillside.solutions/compostclub

My problem: 

Whenever someone stops paying us their monthly subscription product fee, they still have access to a private, password protected page we created to provide them subscription related info. 

If I migrate the password protected page over to a free members area, the same issue exists. 

If I make it a paid members area, they're charged twice. Unless I migrate all customers over to the new platform, but then I lose my various subscription product variances. 

The solution I'm looking for: 

Is there a way to couple active subscription products customers with a members area? 

Meaning, when they cancel their subscription product, they lose access to the member area? 

I need this too for my site Women Entrepreneurs Inc.
