搜了一下，还没有关于体检的详细说明。
我从加拿大citizenship and immigration 网上找到了说明，给大家弄过来看看。
网址如下：http://www.cic.gc.ca/english/work/index.asp
这份说明主要是针对旅游、学生及其工作签证适用。
@对于不超过六个月的旅游和学生签证，不需要体检;
@对于不超过六个月的工作签证，看工作类型：
×工作需要跟人群密切接触的，象是健康领域，中小学教师，幼师，家政，护理等行业需要体检
× 其他的则不需要
@对于超过六个月的各类签证，如果申请人在某些特定国家和地区居住超过六个月则需要体检;
中国位居其中，因此需要。详见附表：Designated Country/Territory List
@体检需要到指定医师处执行
