Can a sponsorship application continue if the sponsor becomes seriously ill or incapacitated mid-process?

Yes, a sponsorship application can generally continue if the sponsor becomes seriously ill or incapacitated while it's being processed — illness on its own does not automatically end a pending application. IRCC continues to assess the application based on the information and evidence on file.

The bigger issue is usually whether the sponsor can still meet the ongoing eligibility requirements tied to their category. For parent and grandparent sponsorship in particular, sponsors must meet an income test assessed against recent tax filings, and a serious illness that affects someone's ability to work or earn income could make it harder to continue meeting that requirement. For spousal sponsorship, income requirements are generally less central, but a sponsor's capacity to sign documents, respond to IRCC requests, or otherwise participate in the process can still matter, especially if incapacity is significant.

Because the impact of illness or incapacity depends heavily on the specific sponsorship category, the stage of the application, and the nature and severity of the condition, this is not something with a single blanket answer. If a sponsor's health has changed significantly during processing, it's worth getting individual advice on how to report the change and what, if anything, needs to be done to keep the application moving forward.
