Hello,
I believe it depends on your residency status. If you are a resident of Canada for tax purposes you will need to file a tax. if you are Emigrant you don't have too.

are you working right now in uae? and is canadian citizen?
I am based in UAE and I am not Canadian Citizen, I am only asking so I can provide people here answers about their questions
If anyone who is considering moving from Canada to UAE, one important thing to consider is " based on your personal circumstances - if you have to or will pay income tax to Canada" then getting a big salary in UAE will be just equal being in Canada too.
1. Tax-Free Salary (now once again this depends on your personal circumstances, let say you cut ties 100% with Canada like no family, no house, no investments, etc then I believe you will be tax-free) but if you have ties then Canada will consider you a factual resident.
2. If you have kids Schools here are very very expensive 18 to 26,000 CAD per Child plus annual bus of +/-2000 CAD
3. There is no single formula for the salary if you know your worth in the marketplace here in UAE and you know how to bargain you can get a very competitive salary - I can say this as I am Asian origin but the package I get overall is among the top side of the total remuneration package.
4. You will get annual airfare - for the family too if you are hired as "family status"
5. Being a Canadian is a plus but not necessarily always "top advantage amongst others" - Here in UAE, they value the Middle East vast Experience.
6. Here you will not get any government subsidy such as CERB, Child Care benefit etc - Starts with your salary/end with your salary.
7. tax-wise you only pay 5% sales tax amongst everything
8. When you end your contract / terminated or resign you must exit the country - no PR status here every 2 years you renew. If you have some serious health problems like AIDS, TB, Hepa then your career is done in UAE.
9. Living expenses - we cannot consider "low" depends on the areas you wish to stay". range from 25-40,000 CAD annually for 3 bedrooms wildly depends on the areas you wish to stay.
10. House Purchase - It's almost impossible (but not impossible - as I personally buy my own unit here than renting as from the start I know I will stay here at least 10 years) for most of the ex-pats owning a home here for several reasons. first, it is mandatory you pay 25% downpayment and 75% finance by the bank plus some extra fees I would say 3 to 5% max. Some people decide not to buy a house/apartment as typical expats cannot be citizens or permanent residents here.
UAE is my home for almost 13 years now, I saw almost everything, its a great country and it is my second home,. but in the end, people move from here to Canada or anywhere else more than just money. Unfortunately, some folks having a challenging start in Canada because they move to Canada without Job and they have to start from the bottom of the ladder but in the end sense of security for their kids that they can go to school for free and for parents in Canada they don't have to worry that they will be sent home (the entire family) if they lose their job. in UAE that the case, end on contract, termination, resignation you have one month, and you're done you need to exit.
I hope I provided everyone with enough information about UAE.
