Sue it is illeagal to ship Frontline spray to Canada and if it is pulled in customs it will be confiscated. It is not an approved product here and lacks the french writing etc. As a side note it is not avilable for sale in California as not approved there, don't know why. I used Ivomec and Ectiban 25 for years with good results as long as I stuck to my program of 3 times a year everyone. To me mite control is all about never letting them get out of hand and if the birds are checked randomly every week while doing chores, they can be kept in check.
