Canadian Paid but living in the UK

I have a dilemma. I will Be moving to income protection insurance 50% of my salary for the next 12 months (paid by Canadian insurance company) on behalf of my IT employer, but will be in the UK as that’s where the best treatment for my condition is, and to Support withdrawal of drug meds Canadian drs put me on. Do I just pay my tax in Canada and call it a day, or do I have to declare something in the UK as I’ll go past 90 days. I will be fully taxed by Canada next year as the 50% starts mid December and I move back to the Uk in January. This could be a hybrid part time move but weighing up options and looking to understand more.
