Having skills not readily available in Canada doesn’t necessarily make a foreign worker suitable to work here — they have to speak the language
Background
Under the Temporary Foreign Worker Program, Canadian immigration law facilitates the hiring of foreign nationals who possess knowledge, talent and skills that are not available in Canada. This program requires an employer to obtain a positive Labour Market Impact Assessment (LMIA) from Employment and Skills Development Canada. However, a positive LMIA does not mean that the foreign national will automatically be issued a work permit. One of the hurdles in obtaining a work permit is demonstrating language proficiency in either of the two official languages, English or French.
