No. Canadian citizenship affects the applicable visa process, while the actual L knowledge, employment and company requirements still need to be met.
Separate exemption from classification
Canadian citizens generally do not need an L visa, but must follow the applicable petition and admission process. Do not interpret a visa exemption as permission to begin any proposed U.S. work.
Relevant project records, process decisions or training evidence may show special knowledge of organizational interests and international application, or advanced knowledge of organizational processes and procedures. Two employees holding a skill is a fact about staffing, and a petition that leans on it alone invites the obvious reply that the company could train a third. The U.S. role must require specialized knowledge of the company’s product, process or procedures rather than general occupational skill. The qualifying employment period, relationship between organizations and business operations remain necessary even when the knowledge account is strong. A company may route difficult questions to an employee for several reasons; the routing practice alone does not establish the classification.
