environment canada just released this summary for july:

AWCN11 CWTO

Updated weather summary for Southern Ontario and the
National Capital Region issued by Environment Canada
At 8:58 P.M. EDT Thursday 31 July 2014.

Four more tornadoes from earlier this month added to Ontario tornado
list.

Continuing investigations on the part of Environment Canada personnel
have led to the addition of four tornadoes to the list for this year.

Scattered thunderstorms rolled across Southwestern Ontario on the
afternoon of Monday July 7. Photographic evidence was provided to
Environment Canada indicating that one of these storms produced a
brief tornado near the norwich area to the south of Woodstock at
around 4 PM EDT. There was no evidence of damage from this tornado
and so it has been rated as an enhanced Fujita scale zero (ef0) event
with winds of at least 90 kilometres per hour.

Between 8 PM and 8:30 PM EDT on Wednesday July 15, two strong storm
cells moved over the North Bay area. Based on photographic evidence,
the first cell generated a waterspout over Eastern Lake Nipissing. A
tornado over a body of water is known as a waterspout. Waterspouts
which form in association with thunderstorms over smaller bodies of
water are included in the tornado database. However, waterspouts that
occur over the Great Lakes are not included in the database unless
they come ashore. Based on video and photographic evidence, the
second cell generated a brief tornado just to the south of North Bay
Airport. Neither event produced any notable impacts and so both have
been rated as ef0 events with winds of at least 90 kilometres per
hour.

At around 6:30 PM on Sunday July 27 near the community of millbank
(about 30 kilometres northwest of Kitchener), a number of weather
spotters reported a funnel cloud. One of the spotter reports
indicated the presence of swirling dust and debris beneath the funnel
cloud. The presence of the swirling debris indicates that, at least
briefly, this was a tornado. No damage was reported in the area after
the sighting and so it has been rated an ef0 tornado with winds of at
least 90 kilometres per hour.

This now brings the total count of tornadoes in Ontario this year to
12. Ontario normally confirms 12 tornadoes each year in a season that
runs from late April until early October.
