Canadian sourcing
Find opportunities to replace foreign components with Canadian suppliers.
MapleBOM identifies the economically important foreign dependencies in your bill of materials — which components, which suppliers, and how much you spend on them each year — so a sourcing search starts from evidence instead of instinct.
MapleBOM does not match components to Canadian suppliers, and it will never invent a supplier match. It produces the shortlist a sourcing search starts from: foreign-origin components ranked by what you spend on them.
BOM uploads are analyzed transiently in memory and are not retained. How this works
The problem
Reshoring starts with a list nobody has.
The instinct to source closer to home is easy. Acting on it needs specifics: which lines are actually imported, which are worth the switching cost, and which suppliers hold enough of your spend to be worth a conversation. That list rarely exists in one place.
Value, not volume, decides where to start
The thousand cheap imported fasteners are not the opportunity. Four assemblies might be.
Supplier concentration shapes the options
If most foreign content arrives through three suppliers, the sourcing conversation is with those three.
Half the list may be unverified
Components with no recorded origin cannot be counted as imported or domestic. They have to be resolved before the list is real.
The core output
The list you cannot build yet.
Components with no established origin cannot be sorted into domestic or imported. MapleBOM ranks them by spend so you know which ones are worth resolving first.
In the sample analysis, 480 components have no established country of origin — but 10 supplier conversations would account for 80% of that exposure.

What you get
A complete provenance profile of one product, in about ten seconds.
-
Overview
Components, suppliers, total purchasing, and how much of it has an established country of origin — by line count and by dollar.
-
Country exposure
Purchasing attributed to Canada, the United States, China, Mexico and every other origin your file names, plus the unverified share.
-
Provenance gaps
Unresolved components ranked by spend, and the suppliers who hold the answers, so the work list is finite.
-
Supplier concentration
Top supplier, top five and top ten as a share of purchasing, with a concentration index and each supplier's origin coverage.
-
Foreign dependencies
The largest components and suppliers behind each non-Canadian origin. Presented as information, not as a verdict.
-
Data quality
Exactly how we read your columns, what we could not interpret, and which figures are affected by missing data.
What MapleBOM will not do
Provenance is only useful if it is true. These are the rules the analysis follows, without exception:
- We never infer country of origin from a supplier, manufacturer, distributor or company nationality. Buying a part from a Canadian distributor does not make it Canadian.
- Anything the file does not establish is reported as Unknown / Unverified, with the reason it is unresolved.
- Country values we cannot interpret are surfaced, not silently dropped or guessed.
- V0 makes no CUSMA, tariff, Canadian-content or Buy Canadian determination. Those require rules and evidence this tool does not yet have.
- Facts you supplied, figures we calculated, and information nobody has are labelled separately throughout.
On the roadmap
What would you like to do next?
None of these are built. They are in private beta, and they are here so you can tell us which one actually matters — we will run it by hand for one product in the meantime.

Built in Canada
An independent project.
MapleBOM is built by Tyson Hamilton, a Canadian software engineer building better trade and supply-chain tools for Canadian manufacturers.
It is early, and deliberately narrow: it reports what your bill of materials establishes, and says plainly what it does not.
Questions, feedback, or interested in trying MapleBOM with your own data?
hello@maplebom.caWant us to resolve the unknowns?
We are working with a small number of Canadian manufacturers on deeper BOM provenance and supply-chain analysis. If unverified origin is costing you time, we would like to hear about it.
