For requests for work permits based on significant economic benefit, where entry into the labour market is concerned,
all practical efforts to obtain ESDC's assessment should be made before C10 is applied. Foreign nationals submitting an application for consideration under C10 should provide
documentation supporting their claim of providing an important or notable contribution to the Canadian economy.
