Few questions to check I’ve understood correctly:
I guess your ITA was under CEC/FSW? You previously applied via OINP but did not get your ITA after PNP? You haven’t also applied to QSW and don’t intend to apply?
I don’t understand the urgency to leave QC for ON. It’s going to take 5-6 months to process your application. What are your fears about the negative impact on EE process from staying in QC?
If you need to write a covering letter then suggest you just say exactly what you did above:
- You currently have a secure job and apartment in Quebec. Your health coverage is in Quebec. Your intention is to move to Ontario. Given the impact of the COVID-19 pandemic on domestic policies and employment opportunities, you have delayed your plans to re-locate to Ontario. Depending on what happens with COVID-19, you would still like to re-locate to Ontario whilst you’re PR application is in progress. You will update IRCC with any new address and employment details in future.
- if there’s family in another province you could stay with in future, you could perhaps mention that too.
This seems entirely reasonable. The immigration officers might raise a flag if you haven’t moved outside of QC prior to CoPR. But they have no grounds to reject your application.
