Answer
In the Name of Allah, Most Gracious, Most Merciful.
All praise and thanks are due to Allah, and peace and blessings be upon His Messenger.
In this fatwa:
Using zakah money to repair an air conditioner or to buy a computer in the mosque depends on whether these things are a priority for Muslims in Canada or not.
In his response to your question, Prof. Dr. Monzer Kahf, Professor of Islamic Finance and Economics at Qatar Faculty of Islamic Studies, states:
The fatwa of permitting the use of Zakah money for mosques in the minority communities is meant to consider such mosques and Islamic centers essential for the preservation of the religion of Muslims, children and adults, who live under adversary conditions as minorities.
Consequently, any activity that falls directly under this preservation falls also under this fatwa.
We also have to keep an eye on the priorities of needs within the Muslim community itself, whether it has any more pressing needs at the time, such as feeding the poor and deprived. The question now is twofold: 1) does an air conditioner in Canada, or a computer come under the main things that preserve the religion of such people? My answer: most likely not, but the local management of the Islamic center must know better; and 2) are there any more pressing needs in the community? Also people in the area should know better.
Almighty Allah knows best.
