There is no list available of medically barring conditions.
Cheers. I've done some more research into this and found enough details to make an informed decision.
Inadmissible codes (M4, M5 and M6)
M4 Inadmissible due to danger to public health, e.g., active infectious tuberculosis.
M5 Inadmissible due to excessive demand on health and social services.
M6 Inadmissible due to danger to public safety, e.g., psychopathic personality.
For all M5 codes, the medical officer will add a descriptive code indicating the nature of the excessive demand:
T9 for excessive demand on social services;
H9 for excessive demand on health services;
E9 for displacement of Canadians who are on a waiting list.
The term "excessive demand" means
(a) a demand on health services or social services for which the anticipated costs would likely exceed average Canadian per capita health services and social services costs over a period of five consecutive years immediately following the most recent medical examination required by these regulations, unless there is evidence that significant costs are likely to be incurred beyond that period in which case the period is no more than 10 consecutive years; or
(b) a demand on health services or social services that would add to existing waiting lists and would increase the rate of mortality and morbidity in Canada as a result of the denial or delay in the provision of those services to Canadian citizens or permanent residents.
In light of the Supreme Court decision in
Hilewitz v. M.C.I. and
de Jong v. M.C.I., and subsequently the Federal Court of Appeal decision in
M.C.I. v. Colaco, officers must consider all evidence presented by an applicant, before making a decision of inadmissibility due to excessive demand on social services. Evidence regarding both ability and intent to mitigate the cost of social services in Canada must be considered, if presented.
Effective December 1, 2014, the updated cost threshold is $6,387 per year. This figure is usually multiplied by five (unless the anticipated length of stay is shorter than five years or there is evidence that significant costs are likely to be incurred beyond that period, in which case the period is no more than 10 consecutive years). This results in the legislated threshold of $31,935.
