The fact you have not met in person and cannot prove that (pics of the two of you together), she will not be able to enter Canada as a visitor since she does not qualify for the extended family exemption. It clearly states you have to have spent physical time together. My suggestion is that you go to Germany to visit her first. Otherwise you will be waiting for Canada to open up the borders to visitors.

I actually went through a similar experience. We applied for a visitor visa for my girlfriend in Indonesia but we have met. She does have a bank account but had minimal funds. I had stated that I would cover all her expenses for a 1 month visit but did not provide enough of my financial information so this application was refused.
I requested the VO's notes through ATIP request and found out the specific reasons: travel history, available funds, employment prospects, ties to home country. We resubmitted and I included my pay stubs for the past 4 months, last 4 bank statements, a letter from her employer granting her permission to be away for 2 months, her home and land title, and an explanation for her limited travel history. It was approved last week and they have requested her passport, which she shipped to them. I included IMM0006 in the section of the application, proof of relationship, along with 4 pictures of the two of us together. At the same time it was approved, they also sent the Travel Exemption Letter so she will be able to board the flight.
