I live in North-Central Saskatchewan. Up until a few years ago I had never seen a tick but knew they were in the area. Due to their lifecycle, I generally avoid doing some of the things that I would normally do (like pick rocks for my garden, geocache, lie on the ground doing close-up photography) until late in July. Late May, June, and early July are when they are most prolific. I have to date only ever had them near, not on me. Hanging out in the grass and in low bushes is like stepping into their house, so checks after venturing back out should become part of your routine. I do believe (but have no hard evidence) that ticks, along with other creepies and crawlies (such as black widows, recluse spiders, and rattlesnakes to name some), are slowly but surely moving further north. We have had some major outbreaks of bedbugs recently as well.
