Unless you are a ticketed mechanic in Canada, you won't be able to name your price.
Most places will not recognize other tickets except for the ones recieved through the Canadian Military.
$28/hr shouldn't be too hard to get though and you may be able to challenge a couple years of your apprenticeship or maybe even the whole ticket to get Journeyman certification and maybe even your inter-provincial red seal. The whole reason most shops want you to have this is alot of shops are mixed fleet so they need to be able to do commercial vehicle inspections. If you just get into an equipment shop though, they may not care.
When I quit wrenching in Canada in '06, I was above $30/hr as a red seal Heavy Equipment Tech. If I had stayed, I'd be around $40 working 8 days on and 6 days off rotation-in town!!
Where were you thinking of living? This will be the biggest factor as to how much you make and what it costs to live there. There is quite a range in pay difference from province to province.
