Question explored with the scientific record
Do any of the vaccines on Canada childhood schedule contain mercury, aluminum, or aborted fetal tissue?
The short version: the evidence you retrieved does not answer the question about what is in Canada's childhood vaccines.
The studies you provided are about entirely different topics. They cover mothers' views on immunization in First Nations communities [1], a case of bullous pemphigoid after a vaccination [2], pertussis vaccine effectiveness in Alberta [3], and a series of lab studies on nanoparticles, cell substrates, and fetal tissue used in biomedical research [4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15]. None of these records list the ingredients of any vaccine on the Canadian childhood schedule. They do not mention thimerosal, aluminum adjuvants, or the use of cell lines derived from aborted fetal tissue in vaccine production.
Because the retrieved evidence is off-topic, I cannot answer your question from it. The question itself is factual and can be answered by looking at the official product monographs for each vaccine on the Canadian schedule. Those documents, published by Health Canada and the manufacturers, list every ingredient. My confidence in the answer I can give from this evidence is not clear because the evidence does not address the question.
