She was questioned in Canada? If I were you Id rather fly out from Kuwait straight to Canada. Have you heard about the POLO? Since you didnt process your application in Philippines (I guess??) they will require you to go through POEA and POLO and I have heard it takes ages to get them processed. Plus another thing is that, if your current work permit in Kuwait is due to expire then you might have a trouble coming back from Philippines to Kuwait since you have a Canada Visa already. I had a friend from Singapore, he got his canada visa approved and went back to Philippines for vacation but was not able to exit as the officer saw the canada visa on Passport. Unless otherwise your Kuwait work visa is not expiring too soon then you may be able to satisfy th eimmigration in Philippines that you need to go back to Kuwait and finish up your terms with your current employer.
On my case I chose to fly from Singapore straight to Canada as I was discouraged by POLO and POEA requirements.
Its all up to you.. Goodluck
