Because co-op waiting lists are long, the wait to meet with a co-op for an interview after applying could range from at least three months to three years or longer. Some co-ops are not even accepting applications for their waiting lists. Those hoping to pay less than full housing charges (and qualify for a subsidy) will usually have a longer wait than those able to pay the full charges.
You may also want to consider applying to a new Community Land Trust (CLT) co-op community and you can learn about which of those co-ops are accepting applications through cltrust.ca.
