you can see the"whites of there eyes" right in the mexican consulate in vancouver. i had dealings with them and the sub consulate in calgary and they were both very helpful. we got our fm3's in calgary and registered them in guadalajara when we got here. you can get it done even quicker in vancouver than calgary.
you can go to the mexican embassy site in ottawa.
why are you so set against getting your information from the proper authorities?
they will tell you that you don't have to count every paper clip or fork in your menaje de casa among other things.
they will also tell you that you need a rental or owner[yours] address in mexico for them to even issue you one. a b&b or hotel address will not suffice[you have to show proof of address.
but go ahead and take advice from 2 americans on a chat board. although they both mean well,i'm sure neither of them have had dealings with the aformentioned consulates.
we managed to cross into mexico with a full pick-up truck and 10 foot trailer with paintings,some antique furniture, 2 dogs, electronics,a motorcycle, an entire wood working shop and a full mechanics tool box. the aduano simply asked to look in the trailer and the pick-up , said adios and away we went after getting our sticker for the vehicles.
