Here is the lowest elevation slice of the Franktown radar at 4:50 pm on September 21, 2018 featuring base reflectivity and velocity as the destructive Dunrobin-Mont Bleu tornado was touching down.
There is also another couplet near Arnprior, then I believe the other Quebec tornadoes occurred within couplets mixed into the heavier reflectivities in the rain shield at the northern end of the radar image.

Tornado Reported Near Jenner, Alberta on October 7 Confirmed
At approximately 2:50 pm MDT on Saturday, October 7th, a brief
tornado was observed 15 km southeast of Jenner, Alberta. Environment
and Climate Change Canada’s Prairie and Arctic Storm Prediction
Centre (PASPC) received multiple reports and photos, however there
were no reports of damage. Therefore, this tornado has been given a
preliminary rating of EF0.
This was considered a landspout tornado that was generated by weak
rotation under a rapidly growing thunderstorm. Landspout tornadoes
do not usually cause significant damage but can still be dangerous
as they can topple trees, damage roofs, or toss debris a short
distance.
PASPC meteorologists are actively seeking pictures of the tornado or
damage it may have caused. Should you have any information regarding
this event, or to report severe weather at any time, please call
1-800-239-0484, send an email to ec.storm.ec(at)canada.ca, or tweet
to (hash)abstorm.

Tornado from Friday September 22.
Last Friday, September 22, a number of thunderstorm complexes
developed over eastern Manitoba during the late afternoon then
crossed the Ontario border in the early evening hours.
One thunderstorm was particularly intense and caused some damage to
a remote cabin and nearby trees on Werner Lake, about 80 km
northwest of Kenora. Subsequent analysis has concluded that the
damage was probably caused by a tornado with maximum winds of 120
km/h, which is an EF-0 on the enhanced Fujita scale.
Details concerning length of the damage path are difficult to
confirm. The damage width is estimated to be 30 metres. Fortunately,
no injuries were reported.
