I could not guarantee that you could do that from Canada either my FIL and partner have really good jobs and they would not be able to do this it does depend on you lifestyle fares from cnada to the UK are not cheap, also the exchange rate like NZ and OZ would worka gainst you so you would be paying double for everything on visits to the UK. FIl has always siad if the conversion was $1 to £1 cost of living would be the same both FIL and BIL came over last week for the chrsitening and both of them could not believe the costs for petrol eating out etc without even converting.
Flights too were expensive for both I think FIL in the end used points that had taken 3 years to save., which is when they lst came out. To pt it in perpective FIL is in IT with vast experience and salary into 3 figures no dependant kids etc, BIL and wife are both lawyers in oz no kids need I say more
