How to determine the building value of a rental property for capital cost allowance purpose?

I purchased a rental property located in Richmond Hill, Ontario, in 2022 and would like to get its building value for the purpose of calculating capital cost allowance.  I've looked through my property tax assessment notices and closing documents, I couldn't find the value breakdown for land and building, all I have is the total assessment value.  Where else could I obtain the building value?  Thanks.
