This is what the e-mail announcing the demise of the FRA flight said:
Additionally, effective October 30, our flights between Calgary and Frankfurt will now be serviced non‑stop by a Lufthansa Group airline, maintaining the same connectivity to Lufthansa’s global network. You will continue to be eligible for Aeroplan earning and redemption, access to Air Canada Maple Leaf Lounges, and Concierge services in both Calgary and Frankfurt when choosing this destination.
So yes flying Discover one should have access to the MLL.
As to the international Aspire lounge, AC no longer provides access. I would be very surprised if Eurowings would, given that it is a so-called "low cost" subsidiary of LH. However some Amex (not the AC one) do provide access. Not that I like that ounge BTW.
