Why the GTA

Close to most of your Canadian customers

About 60% of Canadians live in Ontario and Quebec. From Markham — next to Highways 404, 407 and 401 — ground parcels reach most of that corridor in one to three business days, and the US border is a short drive away.

  • Next-day ground to most of the GTA and southern Ontario
  • Quick access to Montréal, Ottawa and the Quebec corridor
  • Close to US border crossings at Buffalo and Detroit
  • Near Pearson airport and major rail and LTL terminals

FAQ

Common questions

What is a 3PL?

A third-party logistics provider (3PL) stores your inventory and picks, packs and ships your orders for you. 6ixFulfillment is a 3PL for e-commerce brands, based in Markham in the Greater Toronto Area.

Where is your warehouse?

Our warehouse is at 130 S Town Centre Blvd, Markham, ON L6G 1B8 — in the GTA near Highways 404, 407 and 401, with quick ground access to Ontario, Quebec and the US border.

Which sales channels do you work with?

Amazon (FBA prep and FBM), Shopify, WooCommerce/WordPress, Walmart Marketplace, Temu, Whatnot, Poshmark, Etsy, eBay, BigCommerce, Wix, Squarespace, Faire and Best Buy Marketplace — plus CSV or API for anything else.

Which carriers do you ship with?

In Canada we rate-shop Canada Post, Purolator, UPS, FedEx, DHL Express, Canpar Express, Loomis Express, GLS Canada, Intelcom | Dragonfly, UniUni and other regional couriers. US orders are inducted into UPS, USPS, FedEx, UniUni and other US carriers after our daily border crossing. We also book LTL and FTL freight.

How fast do orders ship?

Orders received before 2 PM ET on business days ship the same day. Delivery time then depends on the carrier service and destination.

Do you ship to the United States?

Yes — and it is one of the biggest reasons brands choose us. We truck US-bound orders across the border every business day and induct them into UPS, USPS, FedEx, UniUni and other US carriers, so your US customers receive a domestic US shipment. The same daily crossing handles Amazon.com FBA shipments, LTL and FTL freight.
