Canadian vs. US Optical Suppliers — Duties, Lead Times, and Currency Risk for Canadian Practices

Top Flight Canada · July 20, 2026

Many Canadian optical practices source accessories from US wholesale suppliers — often without a clear accounting of the full landed cost. The advertised price looks competitive, but by the time you've added customs brokerage, duties, currency conversion, and longer lead times, the economics frequently look very different.

This guide provides an honest, practical comparison of domestic Canadian versus US-based optical accessory suppliers — the factors that matter and the questions to ask before choosing where to buy.

The total landed cost problem

When a Canadian practice orders from a US supplier, the invoice price is only the starting point. The true total landed cost includes:

  • Duties and tariffs — most optical accessories imported from the US are subject to Canadian customs duties (rate varies by product classification)
  • Customs brokerage fees — typically $50–$150 per shipment for a licensed broker
  • Currency conversion — the difference between the USD invoice and your CAD bank account, plus the exchange rate margin charged by your bank or credit card
  • Longer lead times — cross-border shipments typically take longer and are subject to customs clearance delays
  • Return friction — returning or exchanging products across the border is significantly more complex and costly than a domestic return

Currency risk

This is the factor most often overlooked. When the CAD/USD rate moves against you — as it has meaningfully in recent years — your effective cost of goods from a US supplier rises without any change in the supplier's pricing. A 5% adverse currency move on a $5,000 order is $250 in additional cost, with no warning and no invoice.

A domestic supplier invoices in CAD, which eliminates currency risk entirely. Your costs are predictable across the full year regardless of exchange rate fluctuations.

Lead times and stockout risk

Cross-border shipments to Canada typically add 2–5 business days to a domestic shipping timeline, plus potential customs clearance holds. For practices running lean inventory, the margin for error on reorders is smaller when your supplier is south of the border.

A domestic Canadian supplier shipping from a Canadian warehouse means your order is subject only to Canadian shipping timelines — typically 2–3 business days to most Ontario locations, 3–5 days for most of Western Canada.

When a US supplier might still make sense

There are legitimate situations where a US supplier is the right choice: a specific product that simply isn't available from any Canadian source, or a supplier relationship built over many years with negotiated terms that make the total cost work despite currency and duty headwinds.

What doesn't make sense is defaulting to a US supplier without ever doing the full landed cost calculation. Many practices that have run those numbers have found that a comparable domestic product — even at a slightly higher per-unit price — comes out cheaper once duties, brokerage, and currency are factored in.
