I'd assume they are everywhere at this point.
I never took the threat seriously, not least because I didn't recognize what they were, and there is some denial from some government agencies, while others are warning of a serious threat.
Here's the thing, besides my supposition that I got very ill from something, and tick borne diseases fit the symptoms (albeit there's hundreds of afflictions that do)...Vets have been warning on pets being very prone to them, and they're seeing many engorged ticks in their practices, and tick-borne diseases....so the logic is clear: If they're susceptible, so are we. Quite often you'll get them from your animals. My GP had to treat the symptoms rather than the cause. Tests are not definitive, and there's a slew of diseases you can catch from insect bites.
I don't like insecticide, but cyclists are especially prone to picking them up, and especially on your ankles if you're cycling or hiking with bike through bush (which I do, since I do a lot of back lane cross-country). So use insecticide folks, but be careful with it. Not on your skin, except for the back of your head and neck, wash that off later, but make sure your socks and shoes are sprayed. You're a magnet otherwise.
Confirmed cases of Lyme disease in Ontario more than doubled this year as blacklegged ticks officially make Greater Toronto home, new public health data obtained by the Star show.
The National Microbiology Lab confirmed this week that for the second season in a row, a blacklegged tick infected with Borrelia burgdorferi — the bacterium that can cause potentially disabling disease in humans and pets alike — was found in Rouge Valley, which spans Durham, York and Toronto.
“Once the ticks are established in the location... they don’t ever leave,” said Curtis Russell, an expert in vector-borne diseases at Public Health Ontario. “Now we just have to make sure to see where they’re expanding to.”
Public health data released to the Star show 304 confirmed cases and 54 probable cases of Lyme disease have been reported in Ontario between January and November this year. In 2014, 149 cases were confirmed and 71 were probable.
Typical symptoms of infection can include fever, headache, muscle and joint pains, fatigue and skin rash. Untreated, the disease can last for years and cause neurological and musculoskeletal damage. In some cases, it can lead to heart infection and death.
“Over the last few years, Lyme disease in Canada has evolved from an unusual and focal issue, to an emergent and expanding problem,” Health Canada warned in a recent report.
What’s especially concerning is the spread of ticks from relatively isolated forests to more densely populated areas. [...]

Don't get hysterical, get safe. Use insecticide wisely and Google on best application. Oddly, most GPs are still in the dark on this. They'll lecture you to "wear a helmet and sunblock" and completely overlook the very real threat from ticks.
Btw: There may be better brands out there, I started using a very well-known name brand (won't mention it here, but you're all familiar with it) and it migrates into your mouth, even if you're careful, and numbs your mouth for a week after application. Don't bother with the citronella ones, they' also leave a taste, don't work that well (for mosquitoes and deer flies) and has to be applied every couple of hours max.
The best I've found is the aerosol can, house brand, at Home Hardware. It contains DEET like the most common brand, but it's the *vehicle* you test, not the DEET, and Home Hdwr uses a less volatile and migratory vehicle. And it's cheaper! Be very careful not to spray it on the front of your face, or breathe the spray, hold your breath and close your eyes when applying to your back and back of head. Do your backpacks and clothes too, try to avoid skin contact, but exposed skin needs protection, so use sparingly there. If you can see it on your skin, you're using too much. Better to re-apply when needed than overdo it. You have to use it on your head due to Deer Flies, which can be a real danger swarming you when cycling.
Insecticide is awful stuff, but a hell of a lot better than getting bitten by bugs and ticks.

By Gregory A. Cummins, D.O., M.S. American Board Internal Medicine Fellow Candidate, American Academy of Wilderness Medicine
Ever notice that your biking game just isn’t up to your usual pub crawl bar-to-bar speed? Been achy, run down, sick? And you only had four microbrews for breakfast? It could be that you’re more of a lightweight than in your younger days. Or, it could be that you picked up a little friend while biking.
Ticks cause more disease in the U.S. than mosquitoes or any other critter you can see with the naked eye. If you mountain bike, you will interact with ticks. Just because you’re bigger, and hopefully smarter, does not mean you will win. Ticks transmit diseases that can kill you. More often, they simply maim and drag you down for a bit. Several friends and fellow mountain bikers I know have been sick from tickborne diseases, including a recent master’s MTB Champion. In fact, I picked up a case of Lyme disease at a family reunion four years ago.
