I don't know that there's a proprietary right. There are certainly legal obligations to use it only for certain purposes under the Elections Act. That's all I can say.
You also mentioned the subsidy. I don't necessarily recommend the subsidy. I think it's something that needs to be examined. I honestly don't know whether parties have the kinds of resources that the evolving threats to cybersecurity require. It's an open question, and I think it's worth considering.
