I never saw a tick in Ontario, and I lived there until only a couple of years ago. Here in Manitoba, they are everywhere. A day spent outside in May or June would always end with a tick inspection session that yielded several hitchhikers, both on me and my dog. They tend to crawl around on you for at least a few hours before settling down for a meal, so you can easily pick one up in short grass and find it on your neck shortly thereafter. I've removed many dozens from myself over the past couple of years, and only two had actually begun to bite...they hadn't swollen up into disgusting blood-filled grapes yet.
We now use a treatment for the dogs that seems to work well (got it from the vet), and even when we find one on a dog now it is usually dead. Permethrin on outdoor clothing works well, but you can't spray everything you wear with the stuff...at the height of the season we can pick up ticks from a mowed lawn around here. If I'm just around the house, in the yard, I'll wear shorts and you can usually feel them if they grab on and start crawling.
The best answer for me is a tip I got from a PH in Africa, where ticks are rampant: Flea and Tick Shampoo, sold for dogs! If I suspect I am especially likely to have a few, maybe after time spent in tall grass, etc., I just take a shower with this stuff, taking care to keep it away from face/mouth/eyes. I scrub down with it, rinse, then re-wash with ordinary soap. I've seen several dead or dying ticks rinsed off me in the shower this way. Still check myself carefully afterwards, but it's always nicer not to find any!
Disclaimer: Yes, I know it's not meant for human use. Yes, I'm sure if I drink a few bottles of it I will regret it. Yes, I probably should wait until it's been tested for a few decades and has government approval. If you want to live forever, you probably shouldn't use it.
