Hi Lisan,
You may wish to check out our legal article on keeping pets in condo:

Depending on which local council governs your area, the by-law may or may not prohibit ownership of dogs, or perhaps just restrict the type of breeds. If the council doesn't prohibit so, then the condo management has no legal right to impose such restriction on its residents, unless a specific animal is causing disturbance to others.
We suggest you check on your council's by-law first. If it does allow, you can inform your condo management of your right to do so, and also obtain your neighbors' written consent that your dog is not causing any annoyance or disturbance to them.
You can also seek the help of the Strata Management Tribunal if an agreement is not reached.
Please refer to the article for full details, and hope it helps.
