Yes. This is to virtually all goods. Not all imports are subject to 35%. By legislation, there are a few exemptions under the general tariff, which is the default tariff that applies when you withdraw the most favoured nation tariff treatment.
So there are some exceptions. For example, goods that already have an MFN rate that is well above 35% would retain those higher rates. Examples would be goods that are subject to Canada's supply-managed system, for example. As well, other exclusions retain an MFN rate. Periodicals would be one example, and certain works of art.
