Montreal brands sell to two languages from day one. A store that treats French as a translation layer loses trust with Quebec shoppers, and a store that ignores English limits growth across Canada and the US. Startup Slang works with Quebec and Canadian brands from our office at 1155 Metcalfe St in downtown Montreal, as a Shopify and Shopify Plus agency with AI and marketing built in.
Work with Montreal and Canadian brands
- Polysleep. An award-winning mattress company from Montreal. We designed and built Woolen Warfare, a Polysleep-branded, competitive king-of-the-hill game in Unreal Editor for Fortnite, to meet a younger audience inside the games they already play.
- Panasonic Prestige. A trilingual microsite in English, Traditional Chinese and Simplified Chinese, built in about a week, with consistent design across very different typefaces and densities. Multilingual commerce is something we have solved under pressure.
- Wellwise by Shoppers Drug Mart. A Canadian health and wellness Shopify store with a deep, specialised catalog organised by need.
- Holigos. A move from Magento to Shopify for a clinically tested product, consolidating shopping into one category and shortening the home page by 60%.

Building a bilingual Shopify store the right way
Language and markets
Shopify Markets and translation apps let a single store serve English and French with language-specific URLs (for example /fr/), hreflang tags and localized navigation. We set them up so search engines index both languages correctly and shoppers land in the right one.
Real French content, not machine output
Product descriptions, collections, emails and policies all need natural French. We use AI to speed up translation workflows, then have every customer-facing string reviewed so it reads as if it were written in French first.
Quebec requirements
Quebec's Charter of the French Language and its privacy law (Law 25) affect how stores present content, consent and personal information. We build stores that make compliance easier, such as French-first content, consent banners and clear privacy information, and we work alongside your legal advisers on the specifics.
Payments, shipping and taxes
GST, QST and HST, provincial shipping rules and cross-border sales to the US are configured in Shopify so totals are correct at checkout.
Why choose a Montreal Shopify partner
Montreal has a strong creative and technical community, and a local partner means workshops in person, French and English communication, and a team that understands Quebec shoppers. With our second office in Toronto, we also support brands expanding across Canada. Our Clutch profile holds a 5.0 rating from 5 reviews.
Beyond the store
Brands like Polysleep show that great e-commerce is not only about the storefront. Interactive experiences, content, AI-powered marketing and support all feed the store. Because development, marketing and AI sit under one roof at Startup Slang, we can plan them together.
