They would have to make a free chat interface that uses Chinese models. It isn't about the technical implementation, it's about the interface and the ease of use.
That might have been the case two years ago, but there is no shortage of decent open source solutions that meet or exceed most business use cases. I am sure some enterprising consulting firm will come along and offer integration of those + Canada located inference infra + OSS models (Chinese, or otherwise). I know that there is at least one Canadian inference provider, Augure, but I haven't tried them yet, as well as a few actual model developers in Canada.
