A tick bite in alberta? diagnosed lyme? when? seems very unlikely - there are no recorded cases in the 30+ years of tracking of a case of lyme disease from a bite _in alberta_. All from exposure elsewhere
(not to say that alberta will stay that lucky forever)
Possible she wasn't in Alberta when she got the tick bite, I'm not 100% certain. She may have been on a trip to Saskatchewan or something but she lives in Alberta and definitely was diagnosed with lyme disease from a tick bite.
Possible the bite happened elsewhere and just wasn't discovered until she got back home though. She does travel around a bit
