Tim,, in quite a few cases, they will not accept a field overhaul by a AME.. The best bet,, is to consult an inspector from transport Canada,, let's just say if they don't accept it,, it would be rather surprissing when someone does an import and they don't accept it.. Another example,, In the US, my Garmin 300 was approved for IFR, It has everything connected to it that it should,, but here in Canada,, not approved. Unless I applied for a 1 of approval,, and that's expensive, so guess what,, it's now VFR only.
