First, here is the raw data, straight from the census reports. It is self-reported religious affiliation.
About the instructions on the census forms (See note 1):
Both versions of the questionnaire used the same wording for the religion question: “What is this person’s religion?” Below the question, a note asked respondents to indicate a specific denomination or religion even if the person was not currently a practising member of that group. [end quote]
That means the reported numbers may still include a significant number of non-practicing Mormons, so I would consider the census numbers as a upper bound on the number of practicing LDS in the various regions.
For comparison, the LDS Church reports current membership in Canada at 199,535. Cumorah.com states the membership at 182,142 as of 2010, with 480 congregations.

The religion information is very near the bottom of an extraordinarily long web page. Scrolling on a tablet will take you forever. Use a laptop/desktop computer where you can drag the scroll thumb.
2011
http://www12.statcan.gc.ca/nhs-enm/2011/dp-pd/index-eng.cfmMost of the tables only list 13 religions and LDS did not make the cut, and are not listed separately. There are tables with 95 religions listed. LDS made that list.
Use the search box to search for catalogue number 99-010-X2011032.
You will probably need to check the box to search through "all content". That choice only comes up when the first search fails. Grrr.
The information for cities is organized by metro area rather than city limits.

LDS is a subgroup under Protestant. The information on cities is organized by metro area.
Note 1:
https://www12.statcan.gc.ca/census-recensement/2021/ref/98-500/016/98-500-x2021016-eng.cfmThis is a bunch of very "down in the weeds" material about how the data was collected, how Stat Can handled correcting for non-response bias and similar topics only a statistician could love. NB: I am not a statistician.
Note 2:
I omitted all derived statistics and only listed raw data because even with just that, it is a large mouthful of numbers. I will do a post later with some derived stats. Here is a taste of what it will have - some derived stats for all of Canada:
2011 LDS percent of population of Canada
105,365 / 32,852,320 * 100 = 0.32%
(NB: that is NOT 3.2%, it is about a third of one percent)
2021 LDS percent of population of Canada
87,725 / 36,991,981 * 100 = 0.24%
(NB again, this is about a quarter of one percent)
Percent decrease in the membership in Canada, 2011 to 2021
(0.32 - 0.24) / 0.32 * 100 = 25%
That is not a typo, and I will be extraordinarily embarrassed if I botched the math, but I was very careful.
***Yes, the census reported percentage of LDS in Canada dropped 25% in the last decade.***
The whistleblower complaint about Ensign Peaks came out in 2019, so that may have affected whether Canadian Mormons still wanted to be counted as Mormons. The current unrest over the funneling of Canadian tithing funds to the BYU schools of course came out after the census, but it likely will result in more members leaving.
And the only large province that showed an increase in Mormons was Quebec. Go figure!
Note 3:
https://www.thestar.com/news/canada/2022/10/26/just-over-a-third-of-canadian-population-reports-having-no-religious-affiliation-new-census-data-shows.htmlThis is an early newspaper article analyzing the general religion figures for Canada. It is interesting to compare the percentage of Canadians that are Sikh, or Muslim, or Hindu, or even denominations like JW. Mormonism is really tiny in Canada, especially unusual since it has been there for well over a century in Alberta and BC.
