I originally posted this on r/homebuildingcanada but got recommended to share it here as well. Will keep both as updated as I can. Last update: February 11, 2025

I started writing this a few days ago, but some of the information was hard to find and took me a while. So there is no "in the event", it is simply happening.

It needs to be mentioned that, as we all know, Canada doesn't do tons of manufacturing, so some of the companies listed here are from outside of Canada but manufacture and create jobs here. I'll leave it to you to make that choice between a Canadian company and a company that manufacturers in Canada.

Please comment below if you know of a manufacturer that I missed!

Fiber Cement

Finex Inc. - Thanks to u/Professional_Arm9160 for finding this, they are a Canadian company based out of Quebec which just opened up a new factory in Quebec last year.

Vinyl

Mitten Siding - Owned by a USA company, but they claim that their Vinyl is made in Canada. Can't confirm any of their other products however.

Kaycan - They sell a few different siding materials. They are owned by a french company Saint Gobain, so look for the little graphic they have guaranteeing that the product was made in Canada.

Metal

Longboard Architectural Products - I am biased here as I work for them, but they are based out of Abbotsford, BC. Full recyclable aluminum products. On the higher end of pricing but do have a residential line launching end of February.

Gentek Building Products - It's worth inquiring about their manufacturing practices for this one, they re-sell lots of different products but are a listed Canadian company with no mention of any US manufacturing. Owned by American company, Associated Metals LLC.

Buchner Manufacturing - Similar to other companies, sells variety of products, some Canadian some not. Looks like their aluminum siding Canadian made.

Dizal - Not 100% sure they are Canadian based, but their parent company, Maibec, is. Worth enquiring if you choose them.

Kaycan - You'll see this name quite a bit on this post, they sell a few different siding materials. They are owned by a french company Saint Gobain, so look for the little graphic they have guaranteeing that the product was made in Canada.

Havelock Metal - Roll-formed Steel siding, their website is super easy to navigate and even have a showroom in ON.

Wayne Building Products - Three different brands that sell steel siding. Lux Architectural Products, Armour Side, and their own custom profiles.

Westform Metals - Long time roll form siding manufacturing, they serve BC, AB and SK. Really cool history on their about us page.
