US –> Canada
If you have a US trademark registration, getting a corresponding Canadian registration is usually remarkable easy and inexpensive.
This is because much of Canadian trademark law and practice is very similar to US law.
However, there are no class-based fees in Canada so the government fee for filing a Canadian trademark application is always $250 CDN regardless of how many products or services (or both) are listed in the application.
Canada does not yet use the NICE classification system. Instead, the goods and services must be described in ‘ordinary commercial terms’. This requires some skill and care to do correctly, but generally, the descriptions in US registrations are a very good place to start.
