US Companies With Employees in Canada

Hiring employees in Canada is exciting, but it also creates HR responsibilities that may be very different from what your US team is used to.

A US offer letter, US employee handbook, or US HR process may not work properly for Canadian employees. Canada has different employment standards, workplace rules, termination obligations, vacation requirements, statutory holidays, leave protections, and provincial legislation.

That means your Canadian employees may need different documents, different policies, and different HR processes.

Sienna HR provides HR services for US companies with employees in Canada, helping them build practical Canadian HR foundations and support their Canadian teams with more confidence.

We help US companies with Canadian employees

Sienna HR supports US-based employers that have employees working in Canada, especially in Ontario, Alberta, and BC.

We can help if you are:

• Hiring your first Canadian employee
• Managing a small Canadian team from a US head office
• Expanding into Canada and unsure what HR documents you need
• Using US employment documents that need to be adapted for Canada
• Cleaning up Canadian HR documents after years of patchwork updates
• Looking for practical Canadian HR support without hiring full-time HR staff
• Setting up HR software or onboarding workflows for Canadian employees

Why US HR documents may not be enough

Many US companies assume their existing HR documents can be lightly edited for Canada.

Usually, it is not that simple.

Canadian employment rules are different, and many requirements depend on the province where the employee works. A document that works in the United States may include language that does not apply in Canada, misses required Canadian policies, or creates confusion for managers and employees.

Common issues include:

• US offer letters used for Canadian employees
• Employee handbooks that reference US laws or agencies
• Policies that do not match Canadian employment standards
• Vacation, overtime, holiday, and leave rules that do not reflect Canadian requirements
• Managers applying US processes to Canadian employee issues
• Canadian employees left out of company-wide HR updates
• HR software workflows built around US-only practices

These issues often stay hidden until there is a termination, complaint, leave request, performance issue, or employee question.

What Sienna HR can help with

We provide practical Canadian HR support for US companies, including:

• Canadian employment agreements
• Canadian employee handbooks / manuals
• HR policy development
• HR compliance cleanup
• HR document reviews
• HR software setup and workflow support
• Onboarding documents and processes
• Manager guidance for Canadian employee issues

Our goal is to help you understand what needs to change, what can stay the same, and what should be built properly for your Canadian team.

Practical Canadian HR support without full Canadian HR headcount

Not every US company needs a full Canadian HR department.

But if you have employees in Canada, you do need Canadian HR documents and processes that make sense.

Sienna HR gives you practical, plain-language support so you can manage Canadian employees without guessing, copying US documents, or waiting until something goes wrong.
