Below are some locations you might consider booking for your recording. Do you have another great space to share?
Get in touch and I will post it here.

Ottawa

• University of Ottawa - Perez Hall features both a small recital hall with decent acoustic and piano and several large ensemble rehearsal spaces.  Contact the department of music for more information.
   
• Orleans United Church - located in the east end of the city the large sanctuary there has a good acoustic and a Yamaha grand piano.  Contact them for more information about renting their facilities.
   
• Southminster United Church - at the corner of Bank and Aylmer, this church has a fine acoustic and a well maintained Kawai baby grand.  They charge extremely reasonable rates for the use of their facility.  You can get in touch with them here.

London

• Bishop Cronyn Center Space - located in the heart of downtown, this church-affiliated concert space is available at a reasonable rate for concerts and recordings.  Contact them for a quote, or more information.
   
• Aeolean Hall - on Dundas St, just east of Adelaide this wonderful hall is best for larger projects. A good acoustic and beautiful piano (available at extra cost) - their website has rates and booking information.

If you are a student at UWO, you many have free or low-cost access to several different spaces in the Faculty of Music through the online room booking system. Follow the link to get instructions on how to use it.  Several rooms you might consider are:

• The Organ Studio (MB18) - A great sounding space with a good piano.  I love the natural reverb in this room: this is one of my favorite spaces to record on campus.
   
• Von Kuster Hall - a 270 seat recital hall with a great acoustic for piano, voice, and string ensembles. This facility may be available for rental through the school, or available after-hours to students there. Read the Hall Policy here.
   
• MB345, MB102, MB104 - all good sounding classrooms with well-maintained grand pianos.  These rooms are frequently used for credit recitals and are a good choice if larger spaces are not available.

Toronto

Spaces in Toronto tend to be expensive: if you have an affiliation with a church or university, check with them first.  Something may be available to you for free through those channels.

• York University - Room 235 is available to students wishing to record.  A large room with a good acoustic and piano, this is a good choice after hours or on weekends.
