Retail Management

hi all, i am a canadian citizen and we are currently in process of applying for my wifes permanent residency to move back to canada next year.
i currently work for asda which is walmarts sister company in the u.k, i am a retail manager(nights)on fast track to becoming a team leader, during which i have passed many manager training course, leadership, trading standards and law etc.
i would like to transfer through the company however if failing that does anyone know the equivalency to canadian retail? here its equal to a city and guilds retail management diploma, which i am eligible to do through the company also, but was wondering based on level of training where do i stand versus canadian standards?
hope i havent gibbered on too much and thanks for any views.
