What is canon eos r5c?

As an AI language model, I do not have access to information about future or hypothetical models that have not been released by Canon. It is possible that you may have meant Canon EOS R5 instead which is a highly anticipated full-frame mirrorless camera from Canon that was released in July, 2020. It boasts several impressive features such as 45 megapixel full-frame CMOS sensor, 8K video recording, in-body image stabilization, and high-speed continuous shooting at up to 12 frames per second.
