Inflated Cost of Children's Aspirin in Canada

I have found it impossible to buy baby aspirin on-line as the Canadian border (probably under the direction of Health Canada) blocks its entry. Has a pharmaceutical company lobbied for this trade barrier? A no-name brand of baby aspirin at Loblaws costs $15 for 180 tablets and a mere $4 on-line. Are we paying Health Canada to make prevention difficult and increase future health care costs? I can't believe we Canadians put up with this.
