Of course it can.
How do you want to do it?
If it is just for yourself, you would need a bylaw created and then you would be required to bear the full cost of the installation.
If you want the OC to do it, this is an improvement and would require a special resolution. Just because you get a special resolution, the issue of connection cost would still need to be addressed. Owners who are happy with electricity may not be keen to have the OC pay out their money for something they may not use.
Remember also that owners would need to pay out of their own pockets internal gas piping and the cost of new appliances.
