I think it’ll be a TL role only (Def not a CEO materialIf you login to your express entry profile and check the AOR pdf, it says:
Specifically, let us know if:
• your personal circumstances change: o e.g. birth or adoption of a child, marriage, divorce, death of a spouse, etc.
• your email address, mailing address or phone number changes
• you change your immigration representative
• you want to withdraw your application
• you lose a job offer or lose a provincial or territorial nomination.
So, yes you have to inform them about your marriage.
Just curious what Leadership role are you expecting? Tech Lead / Project Manager / CTO / CEO?
If its ATL or TL then I think you should be fine. Your responsibilities might still match the NOC. But Project Manager / CTO / CEO is a totaly different category and in my opinion you should inform IRCC.
Also, most people recommend informing IRCC if you change you employer. ie. switch companies.
regarding marriage, I’m really hoping to get married in Canada! But you never know!
