Bed bug spray

@Bumpa
I use permethrin. I have recently purchased at Home Depot in Calgary a tin (blue, in case you are looking through the shelves) of "Blaze Pro Crawling Insect Destroyer". The label lists the contents as ".05% pyrethrin, .20% permethrin, and .25% N-Octyl Bicycloheptene Dicarboximide" (I believe that the latter is a preservative. I used it last year to spray the outside of my backpack and sleeping bag. I shall do the same this year. I didn't get bitten, but I was also very careful where I stayed. Whenever a member of this forum or a pilgrim whom I met said that he or she was at an albergue where the hospitaleros or management seemed indifferent to their complaints about bedbugs, I passed by that location.
Be sure to spray things out of doors and leave them to dry there. Keep the spray away from cats, for which permethrin is very toxic. I will copy @SYates' blessing: "Buen camino sin chinches.

Greetings all. Just sorting through equipment for my trip and found that my spray bottle of Permethrin is missing some how. Amazon and a couple of other sites will not ship to Canada, even though that is how I got the last bottle. My question is to all you Canadians or other nationalities who cannot buy Permethrin in country. What do you use as an alternative to pre spray for clothing or bedding?

I don't.

Eventually that stuff gets into the food chain.

Permethrin is sold in Canada for use on farm animals, so check a local feed store. You probably will want to dilute it to the .5% to 1% or so strength normally used for spraying equipment.

I am a bit concerned about using this stuff, permethrin isn't a good repellent from what I have read. It would probably help stop spreading them around if you do come into contact with them.
