From CIC site:-
Qualified intra-company transferees require work permits and are exempted from the Labour Market Impact Assessment (LMIA) under paragraph R205(a) (exemption code C12) as they provide significant economic benefit to Canada through the transfer of their expertise to Canadian businesses. This applies to foreign nationals from any country, including under the General Agreement on Trade in Services (GATS).
Intra-company transferees with specialized knowledge
Companies are able to transfer Canadians to overseas branches and foreign nationals to their Canadian
branch without a labour market impact assessment. Exemptions for intra-company transferees are also
explicitly stated in some trade agreements that Canada is a party to, such as the North American Free Trade
Agreement and the General Agreement on Trade in Services.
.
.
As a result, foreign nationals entering Canada using this labour market test exemption will be highly-skilled
and truly bring specialized knowledge to Canada.
Some may be candidates to apply for permanent residence
here. These provisions will continue to greatly benefit Canadian companies with operations abroad, allowing
them to compete globally and to provide jobs in Canada.
In a nutshell, i couldn't find any statement/fact on CIC site supporting the fact you have stated, though i couldn't find it otherwise.
I am not indicating that you are wrong, but you may not be right.
